Abbreviated breast MRI
Abbreviated breast MRI is a shortened MRI protocol for breast cancer screening, developed for women with dense breasts, cutting scan time from 17 to 3 minutes.
Abdominal CT
Abdominal CT is a diagnostic imaging method that uses X-ray computed tomography to image the abdominal organs, most often to detect injury, inflammation, tumors, and bowel pathology in emergency care.
Abdominal radiology
Abdominal radiology, also called abdominal imaging, is the radiology subspecialty imaging abdominal organs with ultrasound, CT, MRI, and fluoroscopy; its named journal became Abdominal Radiology in 2016.
Abdominal ultrasound
Abdominal ultrasound is a diagnostic imaging method using high-frequency sound waves through the abdominal wall to visualize organs such as the liver, gallbladder, kidneys, and aorta, first described clinically in 1958.
BI-RADS
BI-RADS (Breast Imaging Reporting and Data System) is a standardized reporting system from the American College of Radiology that assigns breast imaging findings to categories 0 through 6.
Breast ultrasonography
Breast ultrasonography, introduced by John J. Wild and John M. Reid in 1952, uses high-frequency sound waves to visualize breast tissue, detect lesions, and guide biopsies as a standard adjunct to mammography.
Cardiovascular computed tomography
Cardiovascular computed tomography uses ECG-synchronized X-ray CT to image the heart and coronary arteries; its main form, coronary CT angiography, is a first-line test for chest pain.
Cardiovascular magnetic resonance
Cardiovascular magnetic resonance (CMR) is a noninvasive imaging technique that measures cardiac chamber volumes, wall motion, and myocardial fibrosis or edema without ionizing radiation or iodinated contrast.
Chest CT
Chest CT is a cross-sectional imaging method that shows lungs and chest structures in more detail than a chest X-ray, commonly used in emergency settings.
Cobb angle measurement
The Cobb angle is the standard radiographic measure of scoliosis severity, taken between the most tilted vertebrae on a frontal X-ray; curves above 10° define scoliosis.
CT colonography
CT colonography, also called virtual colonoscopy, is a low-radiation-dose CT examination that images the prepared colon to detect polyps and cancer without sedation or an endoscope.
Fetal Weight
Fetal weight (estimated fetal weight, EFW) is the prenatal ultrasound estimate of a fetus's weight, computed from biometry (HC, AC, FL, BPD) via regression formulas, chiefly Hadlock; typical accuracy ±10%, worse at extremes and in twins.
Low-dose chest computed tomography
Low-dose chest computed tomography (LDCT) is a chest CT technique using about 1.5 mSv instead of 8 mSv, used chiefly for lung cancer screening in high-risk smokers.
Lung ultrasonography
Lung ultrasonography is a bedside imaging method using ultrasound at the chest wall to diagnose pleural effusion, consolidation, interstitial syndrome, and pneumothorax without ionizing radiation.
MR arthrography
MR arthrography is a musculoskeletal imaging technique in which contrast material is injected directly into a joint before MRI, most often for the shoulder, hip, and wrist.
Pelvimetry
Pelvimetry is the measurement of the diameters of the maternal pelvis and fetal head, by clinical exam, X-ray, CT, or MRI, to judge whether vaginal delivery is possible.
