Lesion conspicuity, a newly introduced lexicon in the ACR BIRADS supplementary atlas on CEM (2022), lacks sufficient data to correlate with malignancy likelihood. The feasibility of assessing contrast kinetics with CEM remains uncertain, and there is a scarcity of available data. Our research aims to address these gaps. Two radiologists, blinded to pathological reports, independently evaluated 504 CEM enhanced breast lesions with histopathology reports, out of which 176 were benign and 328 were malignant. Subjective qualitative assessment of lesion conspicuity and contrast kinetics was done for each enhancing lesion. The lesion conspicuity was classified as low, moderate, or high. The kinetic behavior of each lesion was categorized into either persistent, plateau, or washout. The distribution of lesion conspicuity among benign and malignant lesions, respectively, was as follows: for low conspicuity, 74.4% versus 25.6%; for moderate conspicuity, 30.6% versus 69.4%; and for high conspicuity, 8.4% versus 91.6%. Regarding contrast kinetics and their distribution between benign and malignant lesions, persistent kinetics was detected in 95.6% compared to 4.4%, plateau kinetics in 43.4% versus 56.6%, and washout kinetics in 3.5% versus 96.5%. Statistically significant differences in distribution between benign and malignant lesions were observed for both lexicons (P < 0.001). The inter-observer agreement for lesion conspicuity (kappa = 0.97) and contrast kinetics (kappa = 0.92) was deemed excellent. The addition of lesion conspicuity and contrast kinetics as lexicons in CEM could enhance its diagnostic accuracy.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no special information regarding the median nerve or its surroundings is provided by clinical examination or electrophysiological testing. The purpose of this study is to evaluate the effectiveness of magnetic resonance neurography (MRN) and ultrasound in identifying changes and abnormalities of the median nerve in carpal tunnel syndrome. The twenty-five patients in this study ranged in age from 27 to 63 years old, with a mean age of 47. There were 18 female patients and seven male patients. All patients were sent to the radiology department from the orthopedics, neurology, outpatient clinic, and neurology department, at Ain Shams Hospital, Faculty of Medicine, Ain Shams University. All of the patients had clinically manifested pain along the median nerve distribution, each of the sixteen patients had hand paresthesia, and four had thenar muscle atrophy. In the current study, Ultrasound exhibits low negative predictive value of 67% and specificity of 67%, but high positive predictive value of 95%, sensitivity of 95%, and overall accuracy of 92%. On the other hand, (MRN) exhibits a low negative predictive value of 60% and a high specificity of 75% in the diagnosis of nerve entrapment, but it also displays a high positive predictive value of 95%, sensitivity of 90%, and overall accuracy of 88%. Regarding the assessment of the recurrence cause and post-surgical evaluation is more reliable by Magnetic Resonance Neurography examination. Magnetic resonance neurography and high-resolution ultrasonography can be utilized to diagnose patients with median nerve entrapment and patients who cannot be diagnosed electrophysiologically. MRN is a more accurate method for detecting the exact location of nerve entrapment and evaluating nerve recovery after surgical intervention than nerve conduction studies and electromyography. Additionally, MRN can be used to identify causes that were not previously recognized based on physical examination and electrophysiological tests.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The liver biopsy is the most crucial procedure for the identification and measurement of hepatic steatosis. By identifying the liver attenuation index (LAI) at CT image with fibroscan controlled attenuation parameter (CAP), hepatic steatosis can be evaluated without the risk of liver resection. Using liver biopsy histological analysis as a reference standard, to examine the precision of the CT liver attenuation index (LAI) and fibroscan controlled attenuation parameter (CAP) for quantitative evaluation of macrovesicular steatosis in living related liver donors. In this cross-sectional study, comparing the CT liver attenuation index & fibroscan controlled attenuation parameter with liver biopsy result for the detection of the steatosis in subject's candidate for liver living donors, 50 subjects were conducted at Ain Shams Specialized Hospital and other private hospitals over about 2 years. Our study reported that liver attenuation index of 9 is the cutoff value in post-contrast CT images with sensitivity 100% and specificity 80% that make it a very good method to exclude donor to have steatosis ≥ 15%, which mean that if donor had LAI index < 9, we can safely do proceed do liver biopsy. Our study reported that CAP measurement had an AUROC OF 0.780, for detecting steatosis ≥ 15%, with sensitivity is only 60% with specificity as CT LAI of 80%, our results consider low compared to other studies, that could be due to small number of donors in our study with steatosis ≥ 15% (five cases from 50 donors) unlike the other studies. When used to estimate the amount of liver fat in liver donors, the examined CAP and CT indices worked equally. But according to multivariate analysis, the only factor strongly linked with hepatic steatosis in a living donors was the CT LAI index. We contend that the combination of CT LS attenuation index and CAP allows for the detection of the degree of hepatic steatosis and can be used as an option to liver biopsy, reserving liver biopsy for those with positive steatosis donors.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elevated transverse relaxation time (T2) serves as a specific indicator of increased myocardial water content, thus becoming a valuable index for myocardial edema. However, conventional T2-weighted CMR sequence exhibits several limitations, primarily providing qualitative information. In contrast, recently developed quantitative T2 mapping techniques overcome these limitations, enabling a more reliable assessment of myocardial edema. These techniques offer the advantage of diagnosing and monitoring myocardial injury without the necessity of contrast agents. Our study aims to add to a growing literature demonstrating the efficacy of quantitative T2 mapping technique to detect and quantify regions of myocardial edema post-myocardial infarction. Native T1 and T2 mapping accurately identified myocardial edema in all patients enrolled in the study. Notably, native T1 and T2 values exhibited a significant elevation in the infarcted myocardium compared to the remote myocardium (for T1: 1295.50 ± 87.65 vs. 1074.95 ± 92.86 ms, respectively; and for T2: 74.63 ± 6.51 vs. 52.53 ± 6.26 ms, respectively; p < 0.0001 for both). Microvascular obstruction was observed in 12 out of 20 patients, affecting one or more myocardial segments within the infarct areas. Among this subgroup, regions with a microvascular obstruction within the infarct zone displayed lower T1 and T2 values compared to areas of infarction without microvascular obstruction (for T1: 1115.05 ± 64.70 vs. 1295.50 ± 87.65 ms, respectively; and for T2: 53.65 ± 3.56 vs. 74.63 ± 6.51 ms, respectively; p < 0.0001 for both). Additionally, we provided reference values for myocardial T1 and T2 specific to our facility’s 1.5 Tesla CMR system, applicable to both infarct and remote myocardium. Parametric T1 and T2 mapping techniques can detect and quantify myocardial edema resulting from myocardial infarction. The presence of microvascular obstruction that results from revascularization injury affects both T1 and T2 values. This information can be used and has broad clinical implications for diagnosis and guiding or monitoring the treatment of myocardial infarction.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study sought to establish whether ultrasound can visualize important/useful diagnostic features and complications of the disease in the same way that MR enterography (MRE) can. The study is a prospective cohort of 133 patients of various disease stages (active and in remission) who had previously been seen by a gastroenterologist. All patients underwent abdominal and pelvic ultrasound examinations, with each of the five intestine segments checked independently for thickening and active inflammation. Complications of fistulas, abscesses, and stenosis were evaluated. Findings at MRE together with ileocolonoscopic results were deemed the standard reference. Ultrasound showed wall stenosis ranging from 5 to 12 mm, with a mean ± SD of 7.73 ± 2.30. A single loop was present in 69.2% of cases. The ileum was the most heavily involved loop portion (66.7%). In 72.9% of patients, stenosis and dilatation were present, whereas 69.7% showed active inflammation. Complications such as fistulas and abscess formation (21.2%) were identified. Ultrasound was found to be an effective tool for detecting stenosis and dilatation in the examined patients, with sensitivity of 84% and 87%, and specificity of 91% and 97%, respectively. A high accuracy of 90.9% was demonstrated for abscess formation. Ultrasound is a noninvasive method that is comparable to MRI for detecting damaged bowel segments and transmural complications such as bowel strictures, fistulas, and abscesses in Crohn’s disease patients.

A comprehensive literature review was conducted to explore current clinical applications and investigational uses of focused ultrasound, aiming to provide an up-todate overview of the field's progress. By employing different combinations of intensity and frequency, focused ultrasound can induce diverse interactions with soft tissues, including tissue ablation, cavitation, and mechanical effects. High-intensity focused ultrasound is utilized for tissue ablation and has received FDA approval for treating medication-refractory essential tremor. Conversely, low-intensity focused ultrasound is employed for neuromodulation and opening the blood–brain barrier, facilitating enhanced drug delivery for treating brain tumors and other neurological conditions. This article reviews ongoing clinical trials investigating focused ultrasound's role in neurological condition treatment. Focused ultrasound holds significant promise for managing and treating various neurologic conditions. Whether employed for tissue ablation or transiently opening the blood–brain barrier to enhance drug delivery, numerous potential applications exist.
