PURPOSE To compare standard coil embolization versus the use of an antireflux microcatheter (ARM) in patients undergoing planning angiography before selective internal radiation therapy (SIRT). MATERIALS AND METHODS A prospective, single-center trial was performed in which 30 patients were randomly assigned to undergo SIRT with coil embolization or the use of an ARM. The coil group underwent ...

Dermal uptake of chemicals at the workplace may contribute considerably to the total internal exposure and so needs to be regulated. At present only qualitative warning signs--the "skin notations"--are available as instruments. An attempt was made to develop a quantitative dermal occupational exposure limit (DOEL) complementary to respiratory occupational exposure limits (OELs). The DOEL refers...

BACKGROUND Reduction of radiation burden of multidetector computed tomography coronary angiography (CTCA) has remained an important task. OBJECTIVE To compare effective radiation dose of low-dose 64-slice CTCA using prospective ECG-triggering versus diagnostic invasive coronary angiography (CA). METHODS 42 patients referred for elective invasive CA owing to suspected coronary artery disease...

OBJECTIVES Computed tomography (CT) use is increasing in the emergency department (ED). Many physicians are concerned about exposing patients to radiation from CT scanning, but estimates of radiation doses vary. This study's objective was to determine the radiation doses from CT scanning for common indications in a Canadian ED using modern multidetector CT scanners. METHODS We conducted a hea...

Computed tomography (CT) has had a massive impact on diagnostic radiology over the past few decades. Serious concerns exist because of increase in effective radiation dose associated with CT scans, which could pose significant health risks. In CT, can be estimated by Monte Carlo simulations. The aim study was to estimate and compare doses for from organ dose-based calculations using tissue weig...

OBJECTIVE To examine in what aspects and to what extent robotic ablation is superior over manual ablation, we sought to design a meta-analysis to compare clinical outcomes between the two ablations in the treatment of atrial fibrillation. METHODS AND RESULTS A literature search was conducted of PubMed and EMBASE databases before December 1, 2013. Data were extracted independently and in dupli...

OBJECTIVE To compare the diagnostic performance and radiation dose between contrast-enhanced CT (ECT) alone, and combined unenhanced and contrast-enhanced CT (UE + ECT) for the assessment of adnexal mass. MATERIALS AND METHODS This retrospective study was approved by the Institutional Review Board. A total of 146 consecutive patients (mean age, 41.1 years) who underwent preoperative unenhance...
