• Radiology involves the use of various imaging techniques such as X-rays, CT scans, MRI, and ultrasound.

• Radiographers are trained professionals who operate imaging equipment and work closely with radiologists to interpret images.

• Radiology plays a crucial role in diagnosing conditions such as fractures, tumors, and internal injuries.

Triphasic Abdomen study is a specialized imaging technique used to evaluate the blood flow in the liver and surrounding organs.

• It involves three phases: arterial, portal venous, and delayed phases.

• The arterial phase captures the early arterial blood supply to the liver, showing enhancement of lesions like hepatocellular carcinoma.

• The portal venous phase highlights the portal vein and hepatic veins, aiding in the detection of liver metastases.

• The delayed phase provides additio...read more

CT number is a quantitative measurement used in computed tomography (CT) imaging to represent the radiodensity of tissues.

• CT number is a unitless value assigned to each pixel in a CT image, representing the attenuation of X-rays by the tissue at that location.

• It is calculated based on the linear attenuation coefficient of the tissue and the attenuation of the X-ray beam.

• CT number is used to differentiate between different tissues based on their radiodensity, helping in diagno...read more
