With the advent of multislice CT more than a decade ago, multislice CT angiography has demonstrated a huge potential in the less invasive imaging of cardiovascular disease, especially in the diagnosis of coronary artery disease. The diagnostic accuracy of multislice CT angiography has been significantly augmented with the rapid technical developments ranging from the initial 4-slice, to the cur...

The criterion standard for the detection of intracranial aneurysms is digital subtraction angiography. MR imaging and CT provide good accuracy in the evaluation of brain arteries and aneurysms. We herein report a case of a ruptured aneurysm at a basilar artery fenestration. The diagnosis was assessed with 16-row multisection CT angiography and was confirmed by using digital subtraction angiogra...

Multidetector (MD) technology has created new dimensions in spatial and temporal resolution in computed tomography (CT) scanning. Multislice CT scanners allow non-invasive coronary angiography within a single breath hold by use of faster gantry rotation times and sophisticated algorithms for retrospective electrocardiographic gating 1 . Four-row CT scanners have shown promising results 2 , even...

Figure 1. CT angiography workflow. CT angiography (CTA) allows arteries and veins in the brain and neck region to be made visible in a way that is significantly less invasive than conventional angiography. To fully comprehend the complex geometry of the vessels, a set of CTA images is often visualized using maximum intensity projection (MIP) or volume rendering (VR). In a MIP or VR image, howev...

The saga of CT coronary angiography continues and new exciting developments are on the horizon. We have witnessed the astounding rapid developments in CT technology from 4-, 16-, 64-, 128-, 256-, to 320-slice acquisition, with tube rotational speed increasing from 250 to 87 ms and with ever decreasing radiation exposure from 20 to ,1 mSv with the preservation of image quality. One would think t...

The advent of multislice computed tomography (CT) has revolutionised the performance of body CT and allowed the development of CT angiography (CTA). CTA is a robust and minimally invasive method of visualizing the arterial vascular system. The newer generation of multidetector scans has allowed for shorter scanning times with no respiratory misregistration at peak vascular opacification followi...

Anomalous left coronary artery from pulmonary (ALCAPA) is a rare congenital anomaly with high rate of mortality in first year life. It one the most common causes cardiomyopathy and myocardial ischemia children. In present scenario, computed tomography (CT) angiography sufficient for diagnosis ALCAPA, eliminating need invasive angiography. CT performed infants suspicion ALCAPA technically challe...

BACKGROUND High volume of intravenous contrast in CT-angiography may result in contrast-induced nephropathy. Intraarterial ultra-low volume of contrast medium results in its satisfactory blood concentration with potentially good image quality. The first main purpose was to assess the influence of the method on function of transplanted kidney in patients with impaired graft function. The second ...
