Therefore, it is essential to promptly identify breast cancer in order to implement a more cautious surgical approach for disease treatment. Breast ultrasonography examination has long been used as a supplementary technique to mammography to evaluate palpable or mammographically detectable breast masses. Presently, Breast MRI has become an essential instrument for the detection and analysis of breast cancer. Diffusion-weighted imaging (DWI) is MRI technique that quantifies the movement of water molecules within tissue. It can provide valuable information about the density, viscosity, integrity of membranes, and microstructure of tissues. This study included sixty patients with Equivocal/high BIRADS lesions, underwent Mammography and /or U/S, CEMRI with DWI. The aim of this study was to disclose MRDWI potency in depiction and assessment of different breast lesions unaccompanied by contrast-enhanced MRI with a view to avoid the high cost of the MRI contrast, lessen the number of needless biopsies and probably reclassify breast lesions of high BIRADS categories. This prospective study included 58 patients (with 60 breast lesions), who came with sono-mammography breast lesions of BIRADS lesions > 2, comparison between sono-mammographic BIRADS and MRI BIRADS was done, where 40 cases were downgraded by MRBIRADS. On paralleling MRDWI unescorted by contrast-enhanced MRI with sono-mammographic BIRADS, 36 cases were downgraded. Correlation between pathology of the biopsied lesions with sono-mammography, MR BIRADS and MRDWI was done as well. Sono–mammography shows 88.9% sensitivity and 61.9% specificity with accuracy of 77.7%. Combined CE –MRI and DWI shows 94% sensitivity and 97.6% specificity with accuracy of 96%. While DWI solely shows 88.9% sensitivity and 90.5% specificity with accuracy of 96%. The cutoff value of ADC for prediction of malignancy was 0.9 with 94% sensitivity, 87% specificity and 83.3 accuracy. CEMRI is un-debatably effective in depicting and discriminating indeterminate breast lesions chiefly when combined with DWI. Yet, with the high expense of the contrast and in the event of contrast contraindications or unavailability, DWI has proven to be a convenient substitute for CE-MRI aiding in rendering the breast lesion BIRADS downgraded with diminishing the unneeded biopsies.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141172963","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}

Endoscopy is the gold standard for diagnosis, but it only assesses mucosal lesions. Magnetic resonance enterography (MRE) can assess disease presence and activity, but it has limitations such as motion sensitivity, long scan time, and high cost. Bowel sonography has been introduced as a non-invasive, practical, safe, and low-cost technique to assess disease activity and complications. In our study we aim to assess the comparability of ultrasound to MRE in evaluation of patients with Crohn’s disease, and its complications. Twenty-five patients with 38 Crohn’s disease affected segments were evaluated by bowel ultrasound (BUS) and MRI enterography (MRE), where BUS and MRE showed equivalent diagnostic performance for disease detection and localization (97.4%, 100%), for sensitivity and specificity of both modalities. Peri-mural fluid (89.5%, 94.4%) and mural stratification loss (100%, 100%) showed high sensitivity and specificity by BUS compared to MRE, while for assessment of mural vascularity, BUS showed high sensitivity and specificity for high grade vascularity (100%, 83.3%), but low sensitivity and high specificity for low and moderate vascularity (0%–62.5%, 81.8%) compared to MRE. Complications including fistulae and abscessed were all correctly identified in BUS compared to MRE. BUS showed comparable results to MRE for identification, localization, assessment of findings related to disease activity, and complications in cases of Crohn’s disease rendering it a viable alternative to MRE.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141172961","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 aim of our study was to evaluate role of perfusion by arterial spin labeling and dynamic susceptibility perfusion in grading of skull base meningiomas. The relative arterial spin labeling (ASL), tumor blood flow (TBF), and tumor blood volume (TBV) ratios showed significant differences between low- and high-grade meningiomas. MRI perfusion is a useful in differentiation between low- and high-grade meningiomas. There is significant correlation between ASL and DSC perfusion supporting possibility of using ASL in clinical practice as an alternative technique to DSC perfusion, particularly for patients with renal impairment where no contrast injection needed.","PeriodicalId":11540,"journal":{"name":"Egyptian Journal of Radiology and Nuclear Medicine","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141152145","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}
