Some GLP-1 agonists, such as semaglutide, are more effective than other weight loss drugs, but are still less effective than bariatric surgery in causing weight loss. [16] GLP-1 agonists' weight reduction effects come from a combination of peripheral effects as well as activity in the brain via the central nervous system . [ 17 ]
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
Modern detail-oriented scans such as high-resolution computed tomography (HRCT) is the gold standard in respiratory medicine and thoracic surgery for investigating disorders of the lung parenchyma . Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses , as well as to assess lymph node status at ...
Breast MRI is a technology typically reserved for high-risk patients and patients recently diagnosed with breast cancer. [3] Lastly, scintimammography is used in a subgroup of patients who have abnormal mammograms or whose screening is not reliable on the basis of using traditional mammography or ultrasound. [4]
Dual source CT is an advanced scanner with a two X-ray tube detector system, unlike conventional single tube systems. [15] [16] These two detector systems are mounted on a single gantry at 90° in the same plane. [17] Dual Source CT scanners allow fast scanning with higher temporal resolution by acquiring a full CT slice in only half a rotation.
GLP-1 drugs like Wegovy are all the rage—but people are quitting them too fast to achieve meaningful weight loss, finds 170,000-patient study Lindsey Leake Updated December 4, 2024 at 5:22 PM
Tomosynthesis, also digital tomosynthesis (DTS), is a method for performing high-resolution limited-angle tomography at radiation dose levels comparable with projectional radiography. It has been studied for a variety of clinical applications, including vascular imaging, dental imaging, orthopedic imaging, mammographic imaging, musculoskeletal ...
All women who undergo breast cancer screening with a mammogram in the U.S. must now find out if they have dense breasts — a risk factor for developing breast cancer.. Starting Tuesday, Sept. 10 ...
