Split-bolus contrast injection protocol enhances the visualization of the thoracic vasculature and reduced radiation dose during chest CT.

Objective: To investigate the visualization of mediastinal lymph nodes during thoracic CT employing a multiphasic contrast media (CM) protocol.

Methods: Institutional review board approved retrospective study consisting of 300 patients with known chest malignancy. Patients were allocated to one of two CM protocols: Protocol A, consisted of dual bolus (Phase 1:100 ml CM followed by 100 ml saline chaser) i.

Effect of chest tube size on pleurodesis efficacy in malignant pleural effusion: a meta-analysis of randomized controlled trials.

Background: Malignant pleural effusion (MPE) develops in approximately 50% of all patients with metastatic cancer. The efficacy of small- large-bore chest tube for pleurodesis in patients with MPE is still not clear.

Methods: We performed a meta-analysis to evaluate the efficacy and safety of chest tube size in the management of MPE.

Synchronisation between contrast media administration and caudocranial scan direction increases visualisation of altered coronary artery blood flow in patients presenting with dual left anterior descending coronary artery.

Coronary CT angiography (CCTA) has the advantage over invasive coronary angiography in that its non-invasive nature and minimal risk on patients. CCTA enables accurate assessment of the entire heart, coronary artery system and thorax, displaying three-dimensional information about the spatial relations of the anomalous vessels and surrounding intraluminal and extraluminal anatomy, and thereby contributing clinically important prognostic information. Dual left anterior descending (LAD) coronary artery consists of of two LAD arteries within the anterior interventricular sulcus (AIVS).

Contrast medium administration and image acquisition parameters in renal CT angiography: what radiologists need to know.

Over the last decade, exponential advances in computed tomography (CT) technology have resulted in improved spatial and temporal resolution. Faster image acquisition enabled renal CT angiography to become a viable and effective noninvasive alternative in diagnosing renal vascular pathologies. However, with these advances, new challenges in contrast media administration have emerged.

Using Ultrasound-Guided Peripheral Catheterization of the Internal Jugular Vein in Patients With Difficult Peripheral Access.

Vascular access is necessary in patients admitted to the intensive care unit and the medical ward. Currently, there are multiple modalities to achieve adequate vascular access, each with their own difficulties and drawbacks. Often, in patients with certain comorbidities, it is difficult to obtain a peripheral intravenous (IV) line, which can lead to multiple failed attempts in achieving access.
