Focused ultrasound relieves fibroid symptoms in women

A noninvasive ultrasound procedure effectively shrinks uterine fibroids and significantly relieves fibroid-related symptoms in women, according to the results of a multicenter clinical trial reported in the June issue of the journal Radiology. Magnetic resonance-g...

PET imaging shows young smokers quick benefit of quitting

...the young," said Tamaki. "This study provided a noninvasive look at the early stages of coronary artery disease in smokers and the recovery time of coronary endothelial dysfunction after giving up cigarettes," indicated Tamaki. Coronary endothelial dysfunction occurs when the heart's blood vessels aren't flex...

Newly identified biomarker detects and regulates spread of brain tumors

...ncology and lead author of the study. "Because few noninvasive methods are available for monitoring CNS malignancies, there is an urgent need to find reliable indicators." Van Meir and his colleagues analyzed 60 cerebrospinal fluid or cyst fluid samples from patients with various CNS diseases using proteomi...

Elasticity imaging identifies cancers and reduces breast biopsies

...ke a manual self-exam but much more sensitive. The noninvasive technique works by gauging how much tissue moves when pushed, and it can detect how soft or stiff an object is. “There are no needles,?Dr. Barr explained. “The patient does not notice any difference from a standard ultrasound.? Dr. Barr used a rea...

Pure carbon nanotubes pass first in vivo test

...searchers are keen to use carbon nanotubes for the noninvasive diagnosis and treatment of diseases such as cancer and atherosclerosis. In the current study, Weisman, Curley and colleagues injected lab animals with water soluble single-walled carbon nanotubes. The nanotubes, whose biocompatible coating was dis...

MIT nanoparticles may help detect, treat tumors

...nd be more visible on an MRI. This might allow for noninvasive imaging of fast-growing cancer 'hot spots' in tumors." Bhatia also is affiliated with the MIT-Harvard Center of Cancer Nanotechnology Excellence. The technique initially is being used to study breast tumors. Bhatia added that it eventually may be ap...

Mayo Clinic Cancer Center: Harnessing the measles virus to attack cancer

...ng in the glioblastoma multiforme trial provides a noninvasive way to monitor viral effects in the tumor," says Dr. Galanis. "When the virus replicates, it produces a marker protein that we can detect in the blood using a clinically-available assay. Repeat brain tumor biopsies for this purpose are not always s...

Patients to benefit from novel technology revolutionizing high-speed molecular imaging

... to define a specific disease signature leading to noninvasive biopsy," he detailed. The D-SPECT camera will provide "a potential breakthrough in organ-specific (heart) SPECT imaging," said George Zubal, SNM's Scientific Program Committee instrumentation and data analysis vice chair and associate professor of di...

UCSD researchers develop 'smart petri dish'

... studies." In addition, they add, their method "is noninvasive and can be performed in real time, representing a significant advantage compared to other techniques for in vitro monitoring of cell morphology," that is, for monitoring cells in the laboratory, outside of humans or animals. ...

Predicting successful outcomes in living-donor liver transplants

...CG test however, had certain benefits. "This novel noninvasive method has advantages in its simplicity, its real-time presentation of results without consuming a lot of time, and its cost-effectiveness," the researchers note. They conclude that being able to predict poor outcomes based on ICG elimination immedia...

Terahertz imaging may reduce breast cancer surgeries

...archers were able to distinguish both invasive and noninvasive breast carcinomas from healthy tissue. Twenty-two excised breast tissue samples were obtained from 22 women who underwent either wide local excision or mastectomy to remove breast cancer. All samples were first sliced and imaged with terahertz light...

New technique puts brain-imaging research on its head

Out of sight, out of mind? Not necessarily

...ranscranial magnetic stimulation (TMS), a harmless noninvasive technique using brief magnetic pulses, was applied to the volunteers' visual cortex -- the area at the back of the brain that processes what the eye sees - to interrupt the normal visual pathway. The volunteers looked at a computer screen, and durin...

Gap-climbing fruit flies reveal components of goal-driven behaviors

...al problems and is less-expensive research. Using noninvasive neurogenetic techniques for the analysis of the underlying motor-control system, Pick and Strauss showed that in order to reach a goal, flies compose complex motor patterns from different behavioral subunits. In their genetic analysis, the researcher...

Researchers Find New Technique To Identify Fetal Genetic Material From Amniotic Fluid

...at fetal monitoring in the womb is now "limited to noninvasive methods such as measurement of uterine size or anatomic evaluation by fetal sonography. In addition, genetic analysis can be performed on amniotic fluid components ? They add that the "cell-free component of the amniotic fluid is discarded after thes...

Whole-body MRI Takes Less Than 20 Min To Scan A Patient's Entire Body For Cancer Spread To Bone

...nd the fact that it’s an MRI scan—which means it’s noninvasive and there is no radiation risk to the patient—whole-body MRI can also detect metastases in other parts of the body besides the bones, such as in the brain, lung or liver,?said Dr. Vilanova. Dr. Vilanova will present the full results of the study on ...

Bioelectronic ‘signatures?hold key to DNA mutations
