Contrast media extravasation: manual versus power injector.

Objective: To compare the incidence and complications of extravasation of low-osmolar nonionic contrast media, injected manually and by the automatic power injector (API).

Subjects And Methods: Three thousand five hundred and sixty patients underwent contrast-enhanced abdominal and thoracic computerized tomography scan in the Department of Clinical Radiology, Al-Amiri Hospital, Kuwait, between June 1998 and December 2002. These patients were prospectively analyzed for contrast media extravasation, its relation to injection rate, cannula insertion and gauge and its complications.

Diagnosis of abdominal hydatid cyst disease: the role of ultrasound and ultrasound-guided fine needle aspiration cytology.

Objective: To retrospectively analyze the role of ultrasound (US) imaging and US-guided fine needle aspiration cytology in the diagnosis and management of abdominal hydatid cyst disease (HCD).

Subjects And Methods: The medical records of 55 diagnosed cases of HCD seen between January 1986 and December 2000 at Mubarak Al-Kabeer Hospital and Al-Amiri Hospital in Kuwait were reviewed for demographic and clinical data, including radiology and serology. The US findings of the patients were classified into four types as follows: type I: single or multiple well-defined cysts, with or without detached or collapsed wall and with or without echogenic contents; type II: single or multiple cysts with peripheral cysts, with or without echogenic contents; type III: solid or semisolid lesions, and type IV: cysts with calcified walls.
