Halved contrast medium dose in lower limb dual-energy computed tomography angiography-a randomized controlled trial.

Objectives: To compare vascular attenuation (VA) of an experimental half iodine-load dual-layer spectral detector CT (SDCT) lower limb computed tomography angiography (CTA) with control (standard iodine-load conventional 120-kilovolt peak (kVp) CTA).

Methods: Ethical approval and consent were obtained. In this parallel RCT, CTA examinations were randomized into experimental or control.

Indirect CT venography of the lower extremities: impact of scan delay and patient factors on contrast enhancement and examination quality.

Objectives: Indirect computed tomography venography (CTV) is often the next imaging modality for deep vein thrombosis (DVT) when sonography is inconclusive. Our aim was to investigate the impact of scan delay and patient factors on contrast enhancement (CE) and examination quality in CTV.

Methods: Patients with clinical suspicion or clinical mimics of DVT in one large hospital were enrolled.

Prophylactic placement of inferior vena cava filters and the risk of death or venous thromboembolism in severe trauma patients: a retrospective study comparing two hospitals with different approaches.

Background: Prophylactic use of inferior vena cava filters to prevent pulmonary embolism in trauma is controversial. The practice varies between hospitals and countries, in part due to conflicting evidence and guidelines.

Purpose: To compare the effects of pulmonary embolism, deep venous thrombosis and mortality in two hospitals using prophylactic inferior vena cava filter placement or prophylactic anticoagulation alone.

Does prophylactic inferior vena cava filter reduce the hazard of pulmonary embolism and mortality in severe trauma? A single center retrospective comparative study.

Objectives: Use of inferior vena cava (IVC) filters in patients following severe trauma without recent history of venous thromboembolism (VTE) is controversial. Our objective was to determine if IVC filter placement in the setting of severe trauma effects the hazard of in-hospital pulmonary embolism (PE), deep venous thrombosis (DVT) and mortality.

Methods: This retrospective study recruited patients from a single Level I Trauma Center between 1/2008 and 12/2013.

[Urography findings after total cystectomy and urinary diversion].

Background: Urinary tract obstruction may damage the kidneys, but the interpretation of intravenous urograms is difficult after a total cystectomy for bladder cancer. There is a need for practical guidelines for image reading.

Material And Methods: Urograms were routinely taken to control 20 patients (18 men) who had been operated for bladder cancer with total cystectomy and urinary diversion between 1999 and 2004.
