Case ReportsOsborne-cotterill lesion: an osseous defect of the capitellum associated with instability of the elbow.
Posterolateral rotatory instability of the elbow is a diagnosis largely made by clinical examination; no relevant radiographic signs have been reported. We have seen four patients with an osseous defect and detachment of a fragment of bone in the posterolateral margin of the capitellum. These patients had chronic posterolateral rotatory instability of the elbow. ⋯ An osseous defect of the posterolateral corner of the capitellum is an uncommon finding that in each instance was associated with chronic posterolateral rotatory instability of the elbow. We termed this lesion the "Osborne-Cotterill lesion." We report our findings in these patients; when this lesion is diagnosed, clinicians should consider posterolateral rotatory instability.

Venous thromboembolism and occult malignancy: simultaneous detection during pulmonary CT angiography with CT venography.
We explored the potential for patients with proven venous thromboembolism or pulmonary embolism (PE) to have occult malignancies detected during the same CT examination. To verify this, we compared the presence of occult malignancies identified on pulmonary artery CT angiography (CTA) and CT venography (CTV) when venous thromboembolism (VTE) was present. ⋯ A high number of malignant tumors can be incidentally discovered on pulmonary artery CTA, even more so with additional CTV. Radiologists should scrutinize scans to pick up unknown malignancies, especially in patients with identified VTE.

Cost-effectiveness of coronary MDCT in the triage of patients with acute chest pain.
Patients at low risk for acute coronary syndrome (ACS) who present to the emergency department complaining of acute chest pain place a substantial economic burden on the U.S. health care system. Noninvasive 64-MDCT coronary angiography may facilitate their triage, and we evaluated its cost-effectiveness. ⋯ CT coronary angiography-based triage for patients with low-risk chest pain is modestly more effective than the SOC. It is also cost-saving in women and associated with low cost-effectiveness ratios in men.

Hepatocellular carcinoma in liver transplantation candidates: detection with gadobenate dimeglumine-enhanced MRI.
The purpose of this study was to retrospectively evaluate the diagnostic performance of dynamic gadobenate dimeglumine-enhanced MRI with explant pathologic correlation in the detection of hepatocellular carcinoma (HCC) in patients undergoing liver transplantation. ⋯ Dynamic gadobenate dimeglumine-enhanced MRI has a sensitivity of 80-85% and a positive predictive value of 65-66% in the detection of HCC. The technique, however, is of limited value for detecting and characterizing lesions smaller than 1 cm in diameter.
