	Guidelines for MRI breast cancer screening not followed in community settings Guidelines are not being followed to ensure that breast cancer screening of high risk women, such as those with a strong family history of breast cancer, includes an additional MRI (magnetic resonance imaging) scan.

	Radiation therapy can be used to treat patients with life-threatening heart rhythm Radiation therapy often is used to treat cancer patients. Now, doctors at Washington University School of Medicine in St. Louis have shown that radiation therapy - aimed directly at the heart -; can be used to treat patients with a life-threatening heart rhythm.

			Bi-annual MRI beats mammograms in detecting breast cancer among women with genetic risk Intensive surveillance including a dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) exam every six months was far more effective in detecting breast cancer in younger women with a high-risk genetic profile than an annual mammogram, according to a research team based at the University of Chicago Medicine and the University of Washington, Seattle.

			3D mammography may help rein in cancer screening costs Although digital breast tomosynthesis, or 3-D mammography, costs more than a digital mammography screening, it actually may help rein in cancer screening costs, according to preliminary findings presented by researchers from the Perelman School of Medicine at the University of Pennsylvania during the 2017 San Antonio Breast Cancer Symposium.

			Bone marrow edema does not increase due to intense physical activity, study finds A recent study published in Rheumatology finds that osteitis/bone marrow edema as measured by magnetic resonance imaging was present in healthy people. However, it did not significantly increase due to intense physical activity.

	TPU researchers create 3D-printed models of children's hearts Scientists from Tomsk Polytechnic University are creating 3D-printed models of children's hearts. They are printed based on magnetic resonance imaging of real patients. These models are used as simulators for cardiac surgeons to plan and pre-work forthcoming operations.

	Study provides new insights into mechanism of tumor survival in glioblastoma A Northwestern Medicine study, published in the journal Cancer Cell, has provided new insights into a mechanism of tumor survival in glioblastoma and demonstrated that inhibiting the process could enhance the effects of radiation therapy.

	Treatment options for outer ear cancer Generally, ear cancer is defined as the uncontrolled development and growth of cancer cells in the ear. Ear cancer is comparatively the lesser prevalent of all types of cancers. Typically, cancer in the ear develops as a skin cancer in or around the external portion of the ear.

	Extramammary Paget’s Disease Classification and Diagnosis As Extramammary Paget’s Disease (EMPD) includes a range of locations, the diagnosis should be made using additional measures such as colonoscopy, mammography, cervical cytology, papanicolau staining, and colposcopy. In addition to biopsies that are performed to find the extent of the disease, some physicians also use noninvasive imaging procedures such as in vivo reflectance confocal microscopy.

	mq-ProFiler: Portable TD-NMR Analyzer for Quality Control and Research Introduction The mq-ProFiler is a compact and portable TD-NMR analyzer that does not have any sample size restriction. It is specifically designed for industrial process/research and quality control. The instrument is fitted with a one-sided magnet and RF probes that can perform 1H-NMR experiments on the surface as well as near-surface volume elements of arbitrarily large samples.

	Researchers discover new way to attack drug-resistant prostate cancer cells In most cases, prostate cancer is cured by surgical removal of the tumor and/or by radiotherapy. However, 20% of patients will need treatment to remove tumor cells but this treatment ceases to be effective after two or three years and the cancer develops further.

	Researchers adopt new approach to treating advanced prostate cancer Scientists have proposed a new approach to preventing the proliferation of prostate tumor cells that are no longer responding to treatment. Prostate cancer can usually be cured via surgical removal of the tumor and/or the use of radiotherapy, but in one-fifth of cases, patients also require treatment with drugs to continue removing tumor cells.

	Studies highlight potential of fMRI applications to detect, treat epilepsy in children Functional magnetic resonance imaging has allowed researchers to map the memory functions that are often impaired within the brains of children with epilepsy.

	Offering lifesaving treatment for cervical cancer results in a net loss for hospitals The evidence is clear: Cervical cancer is best treated with brachytherapy, a form of radiation therapy. Yet the use of this potentially lifesaving treatment has been declining, and a new study from the University of Virginia School of Medicine may explain why.

	Powerful clot-busting drugs reserved for selected patients with deep vein thrombosis Not all patients with blood clots in their legs – a condition known as deep vein thrombosis – need to receive powerful but risky clot-busting drugs, according to results of a large-scale, multicenter clinical trial.

	Maxillofacial Injuries Injuries to the maxillofacial region are fairly common in emergency medicine. This area is of particular importance, because it is dangerously close to the most important organ in the body – the brain. Moreover, the maxillofacial expanse, or put simply, our face, is one of the most imperative elements in our everyday psychosocial wellbeing.

	Ureteric Calculi Research Ureteric calculi are stones in the ureters, which are the narrow muscular tubes that are responsible for the drainage of urine from the kidneys to the bladder. These stones are mostly made up of calcium, but some are composed of struvite (i.e. magnesium ammonium phosphate), while a few are made of uric acid, and a minority of cysteine.

	minispec TD-NMR Analyzer for Determining Oil and Moisture in Seeds and Nuts The minispec benchtop Time Domain NMR (TD-NMR) analyzer provides fast, simultaneous analysis of moisture and oil, with easy calibration.

	Rice scientists develop method to identify patients at high risk of continued seizures before surgery Surgery to remove a part of the brain to give relief to patients with epilepsy doesn't always result in complete seizure relief, but statisticians at Rice University have developed a method for integrating neuroimaging scans to identify patients at high risk of continued seizures before the surgery takes place.

	Modern non-invasive diagnostics can get clear picture of the heart’s condition By no means are only elderly people at risk from heart diseases. Physically active individuals can also be affected, for example if a seemingly harmless flu bug spreads to the heart muscle. Should this remain undetected and if, for example, a builder continues with his strenuous job or an athlete carries on training, this can lead to chronic inflammation and in the worst case even to sudden death.

	Researchers develop molecular beacon to find hypoxic spots in real time Areas of hypoxia, or low oxygen in tissue, are hallmarks of fast-growing cancers and of blockages or narrowing in blood vessels, such as stroke or peripheral artery disease. University of Illinois researchers have developed a way to find hypoxic spots noninvasively in real time.

	Some 3D video games benefit older adults' brains If you're between 55 and 75 years old, you may want to try playing 3D platform games like Super Mario 64 to stave off mild cognitive impairment and perhaps even prevent Alzheimer's disease.

	Scientists develop new method for more effective photothermal treatment of tumors Nanorods made of bismuth sulfide kill tumor cells with heat when they are irradiated with near-infrared light. Chinese scientists are now making these weapons more powerful by remodeling the defect state of the nanorod crystal lattice by adding gold nanodots.

	Scientists gain crucial insights into cause of stuttering One percent of adults and five percent of children are unable to achieve what most of us take for granted--speaking fluently. Instead, they struggle with words, often repeating the beginning of a word, for example "G-g-g-g-g-ood morning" or get stuck with single sounds, such as "Ja" for "January" although they know exactly what they want to say.

	Ureteric Calculi Prognosis Ureteric calculi (i.e. stones in the ureters) is a medical condition that usually causes an abrupt onset of pain in the flank and loin, which may be accompanied by nausea, vomiting and blood in the urine, among other signs and symptoms.

	Keratoacanthoma Diagnosis Small nodules that grow slowly on the surface of the skin are known as Keratoacanthomas. They have a hard and scaly centre which is filled with Keratin, a protein. The skin lesion resembles a volcanic crater with a sprouting center. It is considered a skin tumour, but is not malignant.
