|---|---|
| what is Screening mammography ? | It is performed on asymptomatic females with the use of a two-view protocol, usually medial lateral oblique and cranial caudad, to detect an unsuspected cancer. |
| what is Diagnostic mammography ? | It is performed on patients with symptoms or elevated risk factors. Two or three views of each breast may be required. |
| what is baseline mammogram? | it is the first radiographic examination of the breasts and is usually done before age 40 years. Radiologists use it for comparison with future mammograms. |
| what is interventional radiology? | It is a medical specialty that uses imaging guidance, such as X-ray, ultrasound, CT, or MRI—to perform minimally invasive procedures for diagnosis and treatment. |
| An ___________tube is identified by the diameter of its input phosphor? | Image intensifier |
| Automatic brightness control (ABC) | ___________________maintains the brightness of the image by varying kVp and mA? |
| The chief radiologist | Who is responsible for supervising quality assurance? |
| What is angiography ? | Angiography is an imaging test that uses contrast media and X-rays to visualize blood vessels and evaluate blood flow. |
| What is Venography ? | It is an imaging procedure used to examine the veins and evaluate blood flow through them. |
| Axial tomography | _____________is another name for conventional tomography, as the image plane is aligned parallel to the long axis of the body, resulting in sagittal and coronal sections. |
| First-generation CT imaging systems? | First generation CT imaging system is A finely collimated X-ray beam and a single detector that move and rotate around the patient |
| Second-generation CT scanners ? | It is used a translate-and-rotate design with multiple detectors and a fan-shaped X-ray beam. |
| Third genration CT system? | The main limitation of second-generation CT scanners was their long scan times (20 seconds or more), which was improved with third-generation CT systems. |
| Fourth-genration CT canners ? | Fourth-generation CT scanners use a rotating X-ray tube and a stationary ring of detectors, with a fan-shaped X-ray beam for image acquisition. |
| What is Tomosynthesis? | Tomosynthesis is a type of 3D imaging that uses multiple X-ray images taken at different angles to create detailed slice-like images of the body. |
