This study aimed to provide a classification system for acute pancreatitis by applying the principle that the disease spreads along the retroperitoneal interfascial planes. ⋯ Classification of acute pancreatitis based on CT-determined retroperitoneal extension is a useful indicator of the disease severity and prognosis without the need for contrast-medium enhanced CT.

Multi-detector CT imaging (MDCT) becomes routine imaging modality in the assessment of the postoperative orthopedic patients with metallic instrumentation that degrades image quality at MR imaging. This article reviews the physical basis and CT appearance of such metal-related artifacts. It also addresses the clinical value of MDCT in postoperative orthopedic patients with emphasis on fracture healing, spinal fusion or arthrodesis, and joint replacement. MDCT imaging shows limitations in the assessment of the bone marrow cavity and of the soft tissues for which MR imaging remains the imaging modality of choice despite metal-related anatomic distortions and signal alteration.

Diagnostic value of multislice computed tomography angiography in coronary artery disease: a meta-analysis.
To perform a meta-analysis of the diagnostic value of multislice CT (MSCT) angiography in the detection of coronary artery disease (CAD) when compared to conventional coronary angiography. ⋯ Our meta-analysis showed that MSCT angiography has potential diagnostic accuracy in the detection of CAD. Diagnostic performance of MSCT angiography has been significantly improved with the latest 64-slice CT, with resultant high qualitative and quantitative diagnostic accuracy. 16-slice CT was limited in spatial resolution which makes it difficult to perform quantitative assessment of coronary artery stenoses.

Our experience concerning the use of color Doppler sonography (CDS) in the differential diagnosis of acute scrotum is reported. ⋯ In our experience CDS is an indispensable imaging modality for the clinical assessment of patients with acute scrotum; however, the informations it can afford are operator-dependent and have to be supported by the history and physical exam of the patient. CDS findings constitute probably an important medico-legal support when the necessity of surgical exploration is excluded; anyway, in presence of a clinical suspicion of testicular torsion, even with an apparently normal CDS, the surgical exploration is recommended.

To evaluate the role of chest radiography, single-slice CT and 16-row MDCT in the direct evidence of tracheobronchial injuries. ⋯ Chest radiograph was helpful for the assessment of iatrogenic tracheal injuries. CT detected the site of blunt tracheobronchial injuries in 94% of the cases. Multiplanar 16-row MDCT reconstructions, were essential for the optimal surgical approach.
