Objective: this study aimed to identify the role and diagnostic potential of cardiac magnetic resonance imaging to diagnose and differentiate various types of cardiomyopathy. Patients and Methods: this study included 50 patients with suspected different types of non-ischemic cardiomyopathies referred from outpatient clinic of Cardiology at Al-Hussein University hospital from November 2018 to July 2019. Results: all patients showed mild to moderate mitral regurge (100% of cases), tricuspid regurge was seen in 3 cases (75% of cases) and aortic regurge was seen in 4 cases (50 % of cases). The most value of MRI study of these patients was to differentiate whether if heart failure is related to 1ry dilated cardiomyopathy or other causes such as ischemia as they have different management in each group. Conclusion: CMR is a valuable (minimally or non-invasive) imaging technique in patients with suspected or known to have non-ischemic cardiomyopathies. It helps to identify the underlying cause, predict prognosis and responsiveness to therapy and affect management as well follow-up and most recently as primary prevention diagnostic tool.","PeriodicalId":117142,"journal":{"name":"International Journal of Medical Imaging","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114602064","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}

Asymptomatic CAAs are more common and have a better prognosis. Nevertheless, some of these anomalies are linked with symptoms such as syncope, chest pain, and sudden cardiac death. The aim of the study was to determine the prevalence and describe the coronary congenital anomalies and their variations using coronary CT angiography. MD (320) CT angiography was used to prospectively examine 630 patients with either myocardial ischemic symptoms or suspected coronary anomalies by echocardiography or invasive coronary angiography. Contrast injection with ultra-thin cardiac scanning were then carried out. Images were analyzed with multiplanar reformations (MPR), curved multiplanar reformations (cMPR), maximum intensity projections (MIP) & volume rendering techniques (VR). Coronary artery anomalies were found in 217/630 patients (34.44% incidence), 69 (10.95%) anomalies were of vessel origin with good agreement between CTA and ICA results (K= 0.630), 140 (22.22%) were of vessel course and intrinsic vessel anomalies with moderate agreement between CTA and ICA results (K= 0.448), and 8 (1.27%) were of vessel termination with very good agreement between CTA and ICA results (K= 1.000). from this study we conclude that the prevalence of coronary anomalies is substantially higher with coronary CTA than with invasive coronary angiography and ECG gated multidetector coronary CT angiography allows accurate anatomical assessment of coronary artery anomalies.","PeriodicalId":117142,"journal":{"name":"International Journal of Medical Imaging","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128522342","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}

It is due to mechanical small bowel obstruction (SBO) by a migrated gallstone. we report this observation to illustrate the imaging findings especially in CT scan. A 62-year-old woman was admitted to emergency for acute bowel obstruction. The CT scan has confirmed jejunal bowel distension with fluid levels upstream endoluminal formation which was rounded and well limited, measuring 5 cm of long axis. This training was slightly hyperdense with hypodense areas of fat density. Moreover, there was aerobilia with multiple fistulas between the duodenum (D1) and gallbladder, which was empty. The triad of aerobilia, small bowel obstruction and migrant gallstone was suggestive of gallstone ileus diagnosis. The patient was operated with good evolution. Gallstone ileus is an uncommon presentation of gallstone disease. It is frequently observed in elderly patients with a history of cholelithiasis or cholecystitis. Early diagnosis is crucial and would avoid morbidity and mortality related to this disease. CT scan shows the classical triad of Rigler with pneumobilia, an ectopic stone and mechanical ileus. CT may improve the diagnosis providing important information regarding the exact number, size, and location of ectopic stones and the site of intestinal obstruction or direct visualization of a biliary–enteric fistula, to help clinicians in the therapeutic management of patients.","PeriodicalId":117142,"journal":{"name":"International Journal of Medical Imaging","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131310528","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}

It is very important to know which are the anatomical variants that the patient presents for surgical planning and often for the treatment of the variants that can present as a risk factor. The evidence shows heterogeneity in the prevalence of these anatomical variants and it is not described quantitatively which are the variants that present the greatest relationship as a risk factor. Establishing the multiparametric correlation between at least one of the most frequent anatomical variants of the paranasal sinuses and the development of rhinosinusitis is the most important objective of this investigation. Materials and methods: Case-control study with multiparametric correlation analysis of the anatomical variants of paranasal sinuses as a risk factor in the development of sinusitis. Analysis with measures of central tendency, Xi2, Fisher's exact test, binary logistic regression. Results: The most frequent anatomical variant was the deviation of the nasal septum on the left side (78%). The second most common variant found was the Agger Nasi cells (68%), followed by the protrusion of the Vidian nerve in the sphenoid sinus (52%). The only anatomical variant that could be determined within the regression model was the obstruction of the osteomeatal complex; which is presented as a risk factor with an OR of 16 (95% CI: 6.9-41.3). Conclusions: Obstruction of the osteomeatal complex is a very important risk factor for the development of chronic rhinosinusitis.","PeriodicalId":117142,"journal":{"name":"International Journal of Medical Imaging","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116310149","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}

Eighty patients with pulmonary nodules underwent non contrast CT scan of the chest and dynamic CT perfusion of the chest. Dynamic CT chest perfusion of 80 patients with pulmonary nodules revealed 24 patients had benign nodules of low biological activity, 16 patients had benign nodules of high biological activity and 40 patients had malignant nodules (16 of them had multiple nodules in both lung fields and clinical history of primary extra pulmonary malignancy, so diagnosed as metastatic nodules). Perfusion flow, extraction fraction and blood volume; these indexes showed significant differences between malignant nodules and benign nodules with low biologic activity (P>0.0001) In addition, these indexes showed a significant difference between benign nodules with high biologic activity and those with low biologic activity (P>0.0001) and the perfusion flow was of high benefit for nodules characterization than ejection fraction and blood volume by the higher significant values. CT perfusion compared the effect of therapy (chemotherapy and or radiotherapy) on metastatic pulmonary nodules before and after start of treatment by perfusion parameters (perfusion flow, extraction fraction and blood volume) & colour maps with the clinical data and follow up revealed that both results closely near and raise the efficacy of CT perfusion study in follow up and assessment of treatment response in metastatic pulmonary nodules. It can be concluded that CT perfusion is a feasible non-invasive diagnostic technique able to evaluate the nature of pulmonary nodules and treatment response in patients with metastatic pulmonary nodules.","PeriodicalId":117142,"journal":{"name":"International Journal of Medical Imaging","volume":"380 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122924721","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}
