For diagnostic and therapeutic purposes, multiple imaging techniques can be used to gain more information on a patient’s anatomy. In maxillofacial and neurosurgery, three-dimensional rotational angiography (3DRA) images can provide a detailed view on blood vessels, whereas computed tomography angiography (CTA) images are common for multiplanar interpretation of bone, soft tissue, and blood vess...

During this presentation, the most current post processing techniques available for CT angiography will be reviewed. The audience will understand the application of these tools for optimal image interpretation. Imaging and workflow protocols will be introduced, with the emphasis on improving patient care, as part of a multidisciplinary team.

OBJECTIVE To investigate the clinical applications of coronary CT angiography in patients with suspected coronary artery disease and identify factors that affect CT findings. METHODS Medical records of patients suspected of coronary artery disease over a period of 12 months from a tertiary teaching hospital were retrospectively reviewed. Patient age, sex (male/female), duration of symptoms an...

Pulmonary embolism (PE) is a highly mortal disease, currently assessed by pulmonary CT angiography. True-FISP MRI has emerged as an innocuous alternative that does not hold many of the limitations of x-ray imaging. However, True-FISP MRI is very sensitive to turbulent blood flow, generating artifacts that may resemble fake clots in the pulmonary vasculature. These misinterpretations reduce its ...

Todays, researchers in the field of Pulmonary Embolism (PE) analysis need to use a publicly available dataset to assess and compare their methods. Different systems have been designed for the detection of pulmonary embolism (PE), but none of them have used any public datasets. All papers have used their own private dataset. In order to fill this gap, we have collected 5160 slices of computed to...

Subarachnoid hemorrhage is a devastating condition due to many etiologies, accounting for 5% of all stroke patients. Rupture of an intracranial aneurysms is most frequent causative factor. The diagnosis is usually easy as clinical symptomatology is quite classical, but diagnosis of warning leaks requires increased degree of suspicion. Non contrast computerised scan (CT) of head is initial inves...

PURPOSE Since the first report of TRAM flap reconstruction, there have been numerous studies to reduce complications of elective breast reconstruction. Current methods of preoperative perforator localization can be time-consuming, inaccurate, and imprecise. Thus, we sought to evaluate ultra-high resolution 3D CT angiography for the preoperative mapping of DIEAP flap perforating vessels. METHO...

Cerebellar haemangioblastomas are benign neoplasms which have been reported to have a favourable prognosis. The authors report the experience of Atkinson Morley's Hospital, London with 14 cases of solid haemangioblastoma since the introduction of the CT scan. Death or a poor result occurred in 50% of cases. Incomplete excision carried a high risk of complications. The CT scan appearances were t...

A 58-year-old woman presented with an acute embolic occlusion of the distal basilar artery. She underwent angioplasty and intra-arterial thrombolysis. Angiography performed after recanalization revealed a single perforating thalamic artery. A nonenhanced CT scan carried out immediately after the procedure revealed hyperdense lesions in the bilateral paramedian portions of the thalami, which dis...
