Summary
Multislice CT angiography is a rapid and effective tool for diagnosing brain vascular conditions, especially in children. It offers advantages over MRI and can often replace invasive catheter angiography.
Area of Science:
- Neuroradiology
- Medical Imaging
Background:
- Spiral computed tomography (SCT) and multislice SCT (MSCT) angiography are established methods for studying subarachnoid hemorrhage (SAH).
- MSCT angiography offers advantages such as speed, availability, and high resolution for intracranial vascular imaging.
Observation:
- MSCT angiography was evaluated as an alternative to MR angiography/venography and catheter angiography for intracranial vascular pathologies.
- Seven retrospective cases involving various intracranial vascular conditions were analyzed using MSCT.
Findings:
- Multislice spiral CT provided effective vascular imaging for diverse intracranial vascular pathophysiologies.
- It serves as a valuable alternative for unstable patients, offering faster imaging than other modalities.
Implications:
- MSCT angiography is recommended as the initial imaging choice for intracranial vascular pathologies, particularly in pediatric patients.
- It presents advantages over MR imaging and can often obviate the need for catheter angiography.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:19Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
01:30Radiological Investigation II: MRI and Ventilation Perfusion Scan
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
