Dose optimisation of double-contrast barium enema examinations.

The purpose of the present work was to optimise the filtration and dose setting for double-contrast barium enema examinations using a Philips MultiDiagnost Eleva FD system. A phantom study was performed prior to a patient study. A CDRAD phantom was used in a study where copper and aluminium filtration, different detector doses and tube potentials were examined.

Ultrasound-guided biopsy of abdominal and pelvic lesions in children. A comparison between fine-needle aspiration and 1.2 mm-needle core biopsy.

Background: Tissue diagnosis is mandatory prior to treatment of an abdominal or pelvic lesion in a child.

Objectives: To compare the diagnostic yield and complications of fine-needle aspiration biopsy (FNAB) and 1.2-mm needle core biopsy (NCB) for abdominal and pelvic lesions in children using US guidance.

Yield and complications in percutaneous renal biopsy. A comparison between ultrasound-guided gun-biopsy and manual techniques in native and transplant kidneys.

Purpose: To compare the yield and complications of ultrasound-guided gun-biopsy and manual Tru-Cut techniques in percutaneous renal biopsy.

Material And Methods: A total of 448 biopsies were reviewed. They comprised 124 manual and 131 gun-biopsies in native kidneys, and 111 manual and 82 gun-biopsies in transplant kidneys.
