Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

Scientists illuminate brain tumors with fluorescent nanoparticles

Brain cancer is among the deadliest of cancers. It's also one of the hardest to treat. Imaging results are often imprecise because brain cancers are extremely invasive. Surgeons must saw through the skull and safely remove as much of the tumor as they can. Then doctors use radiation or chemotherapy to destroy cancerous cells in the surrounding tissue.

Ten exceptional health professionals have unique opportunity to influence health reform

Ten exceptional health professionals have been selected as Robert Wood Johnson Foundation Health Policy Fellows for 2009-2010. The ten fellows will utilize their wide range of academic, public health, clinical and community-based experience to provide health policy leadership on Capitol Hill to improve health and health care.

Radiation exposure during interventional procedures a concern for some developing countries

Many facilities in these countries lack the concept of patient dose estimation and dose management, putting patients at a higher risk of developing complications due to overexposure from radiation during interventional procedures, according to a study performed by the International Atomic Energy Agency in Vienna, Austria.

Coronary calcium scoring may predict heart attack risk

Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a study published in the online edition of Radiology.

Artificial intelligence used to diagnose metastatic cancer

When doctors are managing care for women with breast cancer, the information available to them profoundly influences the type of care they recommend. Knowing whether a woman's cancer has metastasized, for instance, directly affects how her doctors will approach treatment -- which may in turn influence the outcome of that treatment.

Obesity associated with increased risk of rapid cartilage loss

Obesity, among other factors, is strongly associated with an increased risk of rapid cartilage loss, according to a study published in the August issue of Radiology.

Topographical brain maps are new frontier to catch early schizophrenia

John Csernansky wants to take your measurements. Not the circumference of your chest, waist and hips. No, this doctor wants to stretch a tape measure around your hippocampus, thalamus and prefrontal cortex.

Many breast cancer patients being kept in the dark on breast reconstruction

Despite the increase of breast reconstruction procedures performed in 2008, nearly 70 percent of women who are eligible for the procedure are not informed of the reconstructive options available to them, according to a recently published report.

Magnetic resonance imaging accurately depicts deep endometriosis

Using magnetic resonance imaging (MRI), radiologists may be able to diagnose deep endometriosis and accurately locate lesions prior to surgery, according to a new study published in the online edition of Radiology.

Antidepressants aid electroconvulsive therapy in treating severe depression

Combining antidepressant drugs with electroconvulsive therapy (ECT) does a better job of reducing symptoms of severe depression and causes less memory loss than using ECT alone, according to a new study by researchers at Wake Forest University School of Medicine and colleagues.

New peripherally inserted central catheter mimics nature

A novel coating being used on a new peripherally inserted central catheter (PICC) from r4 Vascular mimics the cell layer found on natural tissue surfaces.

Rotator cuff calcific tendonitis

A minimally invasive procedure to treat tendonitis in the rotator cuff of the shoulder provides immediate symptom relief to the patient, according to a study published in the July issue of Radiology. The study found that ultrasound-guided nonsurgical therapy significantly reduces pain from calcific tendonitis of the rotator cuff and restores lasting mobility after treatment.

New breast biopsy technique

Researchers have developed a new breast biopsy technique that could lead to decreased procedure times and reduced patient discomfort and morbidity, according to a study performed at Roberts Research Institute, the University of Western Ontario and London Health Sciences Centre, London, ON, Canada.

New biomarker predicts brain tumor's response to cediranib therapy

A report in Cancer Research, a journal of the American Association for Cancer Research, highlights a new biomarker that may be useful in identifying patients with recurrent glioblastoma, or brain tumors, who would respond better to anti-vascular endothelial growth factor therapy, specifically cediranib.

Prophylactic cranial irradiation prevents early lung cancer metastases to the brain

A national Radiation Therapy Oncology Group (RTOG) study led by a Medical College of Wisconsin Cancer Center physician at Froedtert Hospital in Milwaukee has found that a course of radiation therapy to the brain after treatment for locally advanced non-small cell lung cancer reduced the risk of metastases to the brain within the first year after treatment. The study was presented at the American Society of Clinical Oncology annual meeting in Orlando, June 1.

Needle biopsies safe in 'eloquent' areas of brain

After a review of 284 cases, specialists at the Brain Tumor Center at the University of Cincinnati (UC) Neuroscience Institute have concluded that performing a stereotactic needle biopsy in an area of the brain associated with language or other important functions carries no greater risk than a similar biopsy in a less critical area of the brain.

Simple MRI test involving breathing oxygen helps determine cancer therapy success

A simple magnetic resonance imaging (MRI) test involving breathing oxygen might help oncologists determine the best treatment for some cancer patients, report researchers at UT Southwestern Medical Center.

New insights into locally advanced breast cancer

Scientists are reporting two findings that could influence the way researchers screen for, treat and assess prognosis for women with locally advanced breast cancer, an aggressive form of the disease. One finding offers a critical message regarding treatment strategy, they say.

Taking a break from hormones doesn't improve mammograms

Some women take a short break from using postmenopausal hormone therapy before getting their breasts screened for cancer with mammography. They hope to lower their risk of being called back afterward for unnecessary extra breast imaging. But taking a short break from hormones doesn't actually work for this purpose, according to the first large-scale randomized controlled trial to address the question. The READ (Radiological Evaluation and Breast Density) trial of more than 1,700 Group Health women is in the June 2, 2009 Annals of Internal Medicine.

Abraxane prolongs survival in metastatic breast cancer

Research from the Northwestern University Feinberg School of Medicine has found that a less toxic, solvent-free chemotherapy drug more effectively prevents the progression of metastatic breast cancer and has fewer side effects than a commonly used solvent-based drug.
