Role of CT and MRI in diagnosis of pericardial diseases

Background: pericardial diseases are important causes of morbidity and mortality in cardiovascular diseases. CT and MRI are more than adjuncts to echocardiography in pericardial diseases assessment, as they provide an excellent pericardial anatomy delineation and precise pericardial lesions evaluation including; effusion, constrictive pericarditis, thickening, masses and congenital anomalies. Ideal management needs the proper imaging modality choosing ability

Aim of the Study: this study aimed to evaluate the role of CT and MRI versus echocardiography in the diagnosis of pericardial diseases and to show the limitations of each modality

Conclusion: tissue characterization with CMR is superior to cardiac CT and echocardiography. CMR can differentiate tumor from thrombus and is often helpful to assess the perfusion of a pericardial mass with the use of gadolinium contrast. The final diagnosis depends on typical pathologic features

Role of Pet/Ct scan in the assessment of primary and loco regional recurrent breast cancer

Objective: Study the accuracy of 18F-fluoro-2-deoxy-D-glucose [18F-FDG] positron emission tomography/computed tomography [PET/CT] scan in diagnosis of primary and loco regional recurrent breast masses compared with histopathological results and to correlate the results of 18F-fluoro-2-deoxy-Dglucose [18F-FDG] positron emission tomography/computed tomography [PET/CT] with histopathological findings in breast carcinoma patients

Methodology: This study is a prospective study conducted on 24 female patients presented to Ain Shams University Hospitals [oncology, surgery and obstetrics and gynecology departments] with pathologically proven breast cancer underwent PET/CT

Result: SUVmax of the tumor is directly related to the histopathological grade and to the size of the tumor. Invasive ductal carcinoma has predominantly higher SUVmax than invasive lobular carcinomas. Also SUVmax tumor/ SUVaverage liver is more accurate that SUVmax tumor alone. However, no relation between SUVmax and the presence of distant metastasis. 18F-FDG uptake may serve as a prognostic indicator for biological behavior in breast tumors

Role of MDCT in assessment of inflammatory renal disease

Background: Renal inflammatory diseases range from mild to severe, acute to chronic and may be associated with predisposing risk factors like diabetes mellitus, human immunodeficiency virus [HIV], leukemia, vesicoureteric reflux and staghorn calculi. Ultrasound [US] is the initial screening modality and is used for guiding interventions as well. The role of intravenous urography [IVU] has diminished lately, however it still remains the best modality to diagnose calyceal irregularity of early tuberculosis, papillary necrosis and to evaluate congenital anomalies

Aim of Work: The study aim to highlight the value of multidetecter C.T imaging in assessment of renal inflammatory diseases

Conclusion: C.T has the ability to diagnose and assess renal infection site and extension of infection to pararenal fascia, renal infection unilateral or bilateral and infection focal or diffused. CT has important role in assessment of complication and follow up of patients. CT guided FNAB can be done to diagnose renal infection and differentiate between infection
