MRI

Monitoring blood oxygen saturation in the MRI suite can challenge patient care and work flow. Here’s Memorial Hermann Southeast Hospital’s solution.

MR images show significant differences in the early brain development of high-risk infants who go on to develop autism.

Acquiring refurbished imaging machines is a growing trend as practices grapple with decreasing reimbursement or consider the possibility of future consolidations.

Accuracy in evaluating MRIs for acute appendicitis improves after training from more experienced radiologists, and the addition of diffuse weight images also improves reader sensitivity and decreases the amount of time needed to read each image.

In a recent study, fMRI showed that a lack of sleep can lead to a stronger desire to eat junk food. Do you crave unhealthy food when you're sleep-deprived?

Functional MRI scans show sleep-deprived people have a stronger desire for junk food, researchers found.

Using fMRI, researchers have found a strong association between post-stroke depression and functional brain impairment.

MRIs are superior to clinical examination in indicating breast tumor response to pre-surgical chemotherapy.

Breast Imaging and Reporting Data Systems terminology is useful in predicting malignancy in breast lesions that are detected by MRI.

Scientists at the Children’s National Medical Center in Washington, D.C., say they have discovered a protocol that could lead to a hundred-fold increase in MRI speed.

The Echelon Oval has a patient-shaped design, resulting in a 74-cm oval bore - the widest in the industry, the company said.

If a patients shows strong response to images of food (or sex) in an fMRI, they are more likely to gain weight (or have more sex) in coming months, say researchers.

Technique based on whole-brain tractography may predict progress of certain dementias, such as Alzheimer’s disease and frontotemporal dementia.

Imaging reveals grid-like pattern in fiber architecture of the brain - "an important, fundamental discovery." Mapping brain pathways opens doors to better studying brain dynamics and mental health issues.

Adding MRI to breast cancer screening is expensive but may be cost effective for women with a family history of breast cancer - even if they don’t have the BRCA1/2 gene mutation, researchers found.

The addition of two MRI sequences to a common MR angiography technique significantly improves detection of pulmonary embolism and only takes 15 minutes to set up and perform.

MRI is effective in measuring abnormal femoral antetorsion, or in-toeing, and the images can then be used in treatment planning for patients with femoroacetabular impingement.

MRI findings show that astronauts exposed to zero gravity for prolonged periods can develop brain and eye abnormalities.

Radiology and imaging specialists Mukesh Harisinghani, MD, Frank Miller, MD, and David Casalino, MD, discuss an advanced image analysis technology, and the role of prostate MRI in cancer detection, localization, staging, treatment planning and serial monitoring.

With the Magnetom Spectra, Siemens Healthcare plans to make 3-Tesla MRI technology more readily available to smaller and mid-size practices and imaging centers.

Functional magnetic resonance imaging demonstrated changes in brain function and cognitive performance in patients with relapse-remitting multiple sclerosis following a cognitive rehabilitation program.

Diffusion tensor imaging, an MRI technique, showed that significant differences in the brains of high-risk children who go on to develop autism can be seen before symptoms appear.

Diffusion-weighted MRI is the most effective MRI technique to detect and evaluate patient response to platinum-based neoadjuvant chemotherapy for late-state ovarian cancer.

ACR has joined AdMeTech Foundation and the European Society of Urogenital Radiologists to develop standards for the MR Prostate Imaging Reporting and Data System.

Using magnetization transfer ratio (MTR) researchers found a reduction in contrast enhancing lesions, possibly inducing remyelination.

A new magnetic resonance spectroscopy technique provides a definitive diagnosis of brain cancer based on imaging of a protein associated with a mutated gene.

Preoperative MRI helps surgeons make better decisions about nerve-sparing procedures in men with prostate cancer, according to a study in the journal Radiology.

Researchers at Brigham and Women’s Hospital and Tel Aviv University have built a tiny pill camera that would be powered and maneuvered by MRI.

Magnetic resonance imaging can help quantify the loss of gray matter in childhood-onset schizophrenia, bipolar disorder and other psychoses, possibly helping diagnose the cases to become more serious.

Cardiovascular MRI beats SPECT in diagnosing heart disease, according to the authors of a major British study published online on Dec. 23 in The Lancet.
