MDCT for suspected appendicitis: effect of reconstruction section thickness on diagnostic accuracy, rate of appendiceal visualization, and reader confidence using axial images.

Objective: The purpose of this study was to evaluate interpretative performance with different MDCT reconstruction parameters in adult patients with suspected appendicitis.

Materials And Methods: MDCT scans of 212 adult patients obtained in an emergency department with a 64-MDCT scanner were prospectively collected. Acquisition technique included 24 x 1.

Thoracic aortic stent-grafts: utility of multidetector CT for pre- and postprocedure evaluation.

Indications for and experience with placement of endovascular stent-grafts in the thoracic aorta are still evolving. Common pathologic conditions of the thoracic aorta that are amenable to stent placement include penetrating ulcers, aortic dissection, aortic aneurysms, aortic rupture, and congenital abnormalities. Advances in multidetector computed tomography (CT) permit high-quality two-dimensional multiplanar reformation and three-dimensional rendering, which are essential for comprehensive assessment of the thoracic aorta.

Three-dimensional computed tomographic imaging of complex congenital cardiovascular abnormalities.

Primary evaluation of congenital cardiac abnormalities traditionally relies upon echocardiography and conventional angiography, both of which have potential limitations. Echocardiography is an operator dependant study, limited by a small window and patient movement. Conventional angiography is an invasive procedure with an inherent risk of catheter complication such as vessel damage, bleeding, stroke and infection.

Focal FDG uptake in a pancreatic lipoma mimicking malignancy.

Positron emission tomography (PET) using the glucose analog 18-F-fluoro-2-deoxy-D-glucose (FDG) is commonly obtained to stage patients with cancer. Benign lesions can be a source of false-positive PET examinations, leading to incorrect staging and treatment of tumors. Computed tomography can aid in distinguishing between certain benign and malignant lesions.

Concurrent focal hepatic and splenic lesions: a pictorial guide to differential diagnosis.

Although medical literature and differential diagnoses discussions tend to be organ specific, systemic diseases more commonly manifest with multi-organ involvement. Detection of dual organ involvement combined with clinical history narrows the differential to provide a more specific diagnosis. Two organs closely linked are the liver and the spleen.
