Background: multidetector row computed tomography (MDCT) provides reliable diagnostic information on the normal anatomy of the aorta, pulmonary arteries & veins and vena cava, as well as congenital anomalies in pediatric and adult patients. Objective: in this study, we assess the role of multidetector CT scan in the evaluation and its ability to diagnose congenital thoracic vascular anomalies as well as it is importance to recognize these anomalies early for proper treatment and follow up, and also to prevent morbidities and mortalities. Patients and Methods: the study was done in National Heart Institute, Ministry of health Egypt. It included a total of 80 patients (50 males and 30 females, their age ranged between, 2 days to 64 years and the mean age was 11.6±18 years), who underwent MDCT (using GE 16/64-multislice CT) angiography from December 2018 to June 2019 and had diagnosed of congenital thoracic vascular anomalies, or asymptomatic (incidentally discovered). Results: a total of 80 patients had done 16/64-MDCT angiograms were considered to be of adequate diagnostic image quality. Twenty-seven patients diagnosed as systemic arterial (aortic) anomalies corresponding to 33.7% in all cases, the right aortic arch anomalies (9 cases) are represented the most frequent cases (11.2 %). Conclusion: The ability to diagnose congenital vascular thoracic anomalies has evolved tremendously in the past 20 years. Traditional methods of plain radiographs and barium swallow studies as well as invasive angiography have now been supplanted with MR imaging and MDCT, minimally invasive methods that provide superb resolution and a large field of view.
Background Fibroadenomas are one of the most common benign diseases of the breast varying in number and size in all quadrants of the breast. Less than 2% of lesions with the typical ultrasound features of a fibroadenoma, are found to be malignant on biopsy. Aim of the Work To evaluate the diagnostic performance of combined ultrasonography and strain elastography and to compare the imaging characteristics of fibroadenomas with other benign and malignant mimics and assess the results by histopathological characteristics. Patients and Methods Type of Study: Cross-sectional study. Study Setting: The study was conducted at Ain Shams University Hospitals, Radiodiagnosis department. Study Period: 6 months (From March 2020 till September 2020). Study Population: Female Patients with breast lumps. Results Ultrasound elastography combined with B-mode ultrasonography had shown variable degrees of sensitivity and specificity. However, in our study it showed high sensitivity and specificity as compared to other studies. The most reliable tool in our study was the strain ratio having the highest sensitivity and specificity. Conclusion Strain elastography combined to B-mode sonography improves the diagnostic performance of differentiating benign from malignant well circumscribed breast lesions with an additional benefit of preventing unnecessary biopsies and speeding up the diagnosis of malignant lesions instead of follow up of the patient for early diagnosis of malignancies.
Introduction: Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide with an annual occurrence of one million new cases. An etiologic association between HBV infection and the development of HCC has been established. Hepatitis C virus is also proving an important predisposing factor for this malignancy, the use of minimally invasive Percutaneous ablative technique (e.g. Radiofrequency (RF) and Microwave ablation (MW) has gained great momentum and because of the drawbacks of RF ablation, several groups have successfully proved the efficacious nature of Microwave ablation in the treatment of hepatocellular carcinoma. Aim of the Work: The aim of this work is to highlight the role, the principles and the applications of percutaneous Microwave Ablation in Hepatocellular carcinoma. Methods: The studied group included 30 patients (25 men and 5 women) with hepatocellular carcinoma. All patients underwent microwave ablation for the hepatocellular carcinoma. Results: The results of the procedures will be assessed as regarding sizeand enhancement of the lesion (s) on triphasic CT abdomen before the procedure and at the follow up at one month as well as the Alpha fetoprotein levels. Conclusion: MWA technique represents a safe, fast and efficacious way to perform hepatic ablation in patients with HCC. Initial results are encouraging; however, longer follow-up is needed for further classification of our results.
