Intrahepatic biloma formation (bile duct necrosis) after transcatheter arterial chemoembolization.
The purpose of our study was to discuss the incidence, predisposing factors, and clinical course of intrahepatic biloma after transcatheter arterial chemoembolization for hepatic tumors including hepatocellular carcinoma and metastatic liver tumor. ⋯ Biloma formation was significantly more prevalent in the metastatic lesion group than in the hepatocellular carcinoma group. Significant prognostic factors for biloma formation in patients with hepatocellular carcinoma were tumor size of less than 5 cm, bile duct dilatation, proximal injection site, repeated injection with frequency of less than 3 months, and injection of a suspension of anticancer drugs.

Evaluation of emergency CT scans of the head: is there a community standard?
This study was designed to assess the accuracy of general radiologists in the interpretation via teleradiology of emergency CT scans of the head. ⋯ The rate of significant discordance between board-certified on-call general radiologists and neuroradiologists in the interpretation of emergency CT scans was 2%, which was comparable to previously published reports of residents' performance. The pituitary gland may be a blind spot, and additional attention should be focused on this area.

The purpose of our study was to summarize the CT features of pulmonary metastases in angiosarcoma in 24 patients. ⋯ A variety of CT features were associated with metastatic angiosarcoma of the lung. The common CT manifestations of metastatic angiosarcoma were multiple solid nodular lesions and multiple thin-walled cysts that were often accompanied by hemorrhagic change.

CT-guided transthoracic needle aspiration biopsy of small (< or = 20 mm) solitary pulmonary nodules.
The purpose of our study was to determine the diagnostic accuracy and to analyze the factors influencing the diagnostic accuracy and incidences of pneumothorax and chest tube insertion rates for percutaneous CT-guided needle biopsy of small (< or = 20 mm) solitary pulmonary nodules. ⋯ CT-guided transthoracic needle aspiration biopsy is a useful diagnostic tool for small solitary pulmonary nodules smaller than 20 mm in diameter. The diagnostic accuracy is significantly improved for large (> 10 mm) lesion size and short (< or = 40 mm) needle path length.
