Conventional magnetic resonance imaging (MRI) may be an effective alternative to minimally invasive MR arthrography for the diagnosis of hip labral tears, a common cause of hip pain, according to a study presented May 7 at the ARRS 2010 Annual Meeting in San Diego, CA. A hip labral tear involves the rim of tissue that surrounds and deepens the hip joint. Symptoms include hip pain or a "catching" sensation in your hip joint. Diagnosing hip labral tears often involves the use of MR...

Computed tomography (CT) scans are superior to standard radiography (X-rays) for the detection of pelvic fractures, according to a study presented May 7 at the ARRS 2010 Annual Meeting in San Diego, CA. CT scanning combines special X-ray equipment with sophisticated computers to produce multiple images of pictures of the inside of the body. The study, performed at Allegheny General Hospital in Pittsburgh, PA, included 132 patients with pelvic fractures who were evaluated using standard X-rays...

Doctors can use ultrasonography (ultrasound) to evaluate and diagnose muscular trauma in professional athletes on-site, which helps them to determine whether or not a player's injuries are severe enough to take them out of the game, according to a study presented May 6 at the ARRS 2010 Annual Meeting in San Diego, CA. "Muscular trauma is very common in athletes, especially soccer players," said Ashok Kumar Nath, MD, lead author of the study. "Ultrasound is a readily available, radiation free...

When trauma patients receive a computed tomography (CT) scan of the chest, abdomen, and pelvis, a technique called CT spine reformatting eliminates the need for X-rays of the thoracic and/or lumbar spine to detect spinal fractures. This technique can lower cost and overall patient radiation exposure, according to a study presented May 6 at the ARRS 2010 Annual Meeting in San Diego, CA. CT spine reformatting is performed by a CT technician after a CT scan is complete. It helps the radiologist...

Z-axis modulation can significantly reduce the radiation dose associated with unenhanced computed tomography (CT) scans of the head, according to a study presented May 6 at the ARRS 2010 Annual Meeting in San Diego, CA. Z-axis modulation is a simple technique that radiologists can use to adjust the radiation dose and obtain optimal image quality during CT scans. "As radiologists, we are constantly looking for ways to reduce the radiation dose associated with advanced imaging exams such as CT....

Preoperative prostate magnetic resonance imaging (MRI) can help urologic surgeons spare the neurovascular bundle (NVB) (which controls a man's erectile function and continence) during a robotic assisted laparoscopic prostatectomy (RALP) for the treatment of prostate cancer, according to a study presented May 6 at the ARRS 2010 Annual Meeting in San Diego, CA. RALP is becoming increasingly common for the treatment of prostate cancer. "However it is limited by a lack of haptic feedback (loss of...

Fluoroscopic (X-ray) guided steroid injections offer a safe and effective alternative to the conventional treatment of hamstring tendonitis, according to a study presented at the ARRS 2010 Annual Meeting in San Diego, CA. Conventional treatment includes rest, anti-inflammatory drugs, and physical therapy. Hamstring tendonitis refers to inflammation (pain, swelling, warmth, redness, and dysfunction) in one or more of the hamstring tendons. It is relatively common in a multitude of track and...

Whole body magnetic resonance imaging (MRI) should be the imaging modality of choice for the detection of breast cancer metastases (when the cancer has spread beyond the breast) as it is highly accurate and can detect bone metastases while a patient is still asymptomatic (shows no symptoms), according to a study presented May 6 at the ARRS 2010 Annual Meeting in San Diego, CA. Whole body MRI is a noninvasive medical test that helps physicians diagnose and treat breast cancer. Breast cancer...

Researchers have developed a computer-based system that can automatically track patient-specific radiation dose exposure (based on a patient's size and weight) on every patient that receives a computed tomography (CT) scan, providing patients with a way to start tracking their cumulative health care-related radiation exposure, according to a study to be presented at the ARRS 2010 Annual Meeting in San Diego, CA. CT studies account for about 50 percent of the radiation dose exposure...

Researchers have developed an automated 3-D mapping and labeling system that reduces scan time and improves the work flow, efficiency, and accuracy of routine freehand ultrasound exams, according to a study presented at the ARRS 2010 Annual Meeting in San Diego, CA. "The labeling and measuring of free hand ultrasound images are operator dependent, time consuming, and are usually manually performed," said Calin Caluser, MD, lead author of the study. "The new 3-D mapping and labeling system...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
