Safety guidelines are released for magnetic resonance imaging.
Serious and sometimes fatal patient injuries associated with magnetic resonance imaging (MRI) procedures are an ongoing safety concern. Issues might include burns from electrodes and cables during examinations, injuries in patients with implanted neurologic stimulators, burns in patients wearing transdermal patches, or death from being hit by metallic objects...

Clinical utility of breast magnetic resonance imaging in patients presenting with primary breast cancer.
Since magnetic resonance imaging (MRI) of the breast has been shown to be sensitive in identifying the extent of the primary tumor and other foci of cancer, we examined its clinical utility in the surgical management of breast cancer patients. From January 2004 to April 2007, 117 patients with...

Estimation of thigh muscle mass with magnetic resonance imaging in older adults and people with chronic obstructive pulmonary disease.
Sarcopenia refers to the progressive decline in muscle mass, strength (force-generating capacity), and quality that occurs with aging (1) and is related to physical disability, impairments in function and mobility, and frailty in older adults. (2-4) In a large epidemiological study, (2) it was estimated that approximately 50% to...

Fetal magnetic resonance imaging--the new horizon in fetal anomaly screening.
Magnetic resonance imaging (MRI) has been used extensively in neonatal imaging to further characterise abnormalities identified on ultrasound (US) or computed tomography (CT) scan. This technological success was followed by use of MRI in fetal imaging. The first fetal MRI (FMRI) was performed in 1983 in the USA. (1)...

Tricuspid valve mass: magnetic resonance imaging findings/Trikuspit kapakta kitle: manyetik rezonans goruntuleme bulgulari.
Giris Manyetik rezonans (MRI) ile goruntuleme teknigi, radyoaktif yayilim olmadan, noninvazif bir sekilde manyetik radyo dalgalan ile yapilan bir goruntuleme teknigidir. Diger standart noninvazif metodlar arasinda ekokardiyografi ve bilgisayarli tomografi (BT) sayilabilir. Bazi vakalarda ekokardiyografik incelemelerde yanlis pozitif veya negatif sonuclara da rastlanmaktadir (1, 2). Bilgisayarli tomografi...

Functional magnetic resonance imaging evaluation of bilateral brain activation in Chinese speech.
Abstract Objective: To investigate the cerebral hemispheric representation of Chinese subjects employing functional magnetic resonance imaging during verbal fluency tasks. Patients and Methods: Healthy subjects were presented stimuli of the word categories animals, fruit, occupations. Each had to respond by saying aloud in Chinese any...

MRI shows brain changes prior to MCI diagnosis: the Dartmouth group's research is aimed at broadening the use of magnetic resonance imaging.
PHILADELPHIA -- Magnetic resonance imaging has the potential for detecting very early brain changes related to memory impairment, Andrew J. Saykin, Psy.D., reported at the Ninth International Conference on Alzheimer's Disease and Related Disorders, presented by the Alzheimer's Association. New data from the longitudinal Dartmouth Memory and...

Magnetic resonance imaging evaluation of the ulnar collateral ligament in young baseball pitchers less than 18 years of age.
Abstract Introduction: It has been shown that the asymptomatic, dominant elbow of professional baseball pitchers can demonstrate magnetic resonance (MR) imaging signal abnormalities of the ulnar collateral ligament (UCL) consistent with a strain. The purpose of this study was to determine if younger, asymptomatic, adolescent baseball pitchers...

Magnetic resonance imaging of ulnar nerve abscess in leprosy: a case report.
Summary A 14 year old girl on multidrug treatment for borderline tuberculoid leprosy presented with a swelling in her left arm and soon thereafter developed ulnar claw hand. MRI showed a well-defined ovoid lesion arising from the left ulnar nerve, isointense to muscle on T1W images and hyperintense on...
