New point scale to ascertain the stroke recovery

...w method is based on brain scanning using magnetic resonance imaging (MRI), a stroke assessment test and the number of hours between the onset of the stroke and the MRI to determine the severity of the stroke. The size of the stroke abnormalities in the brain as a result of blood clot can be measured using th...

Ecstasy shrinks brain!!-researchers unveil the secrets of MDMA.

...mparing the blood flow in the brain using magnetic resonance imaging of their brains of dug users and then comparing them with brain scans of similar aged non-users."The longer a person uses ecstasy, their brain shrinks," said Dr. Linda Chang. The neurotoxic effects of the drug appear to decrease several are...

A new drug for cancer

... tumour will start to wither and die.// Magnetic resonance imaging studies reveal that DMXAA reduces the blood flow to a tumour. The new drug will probably be used in combination with other anti-cancer drugs. DMXAA will strike the first blow, weakening the cancer by starving it of blood. Then, hopefully, oth...

The feel of pain

...e, scientists from Oxford University used magnetic resonance imaging to monitor the brain activity of a group of people as they felt a series of painful sensations on their hands, each signaled in advance by a coloured light. This allowed them to show something no research team had demonstrated before - there...

The cancer-fighting gene

...on professor Rachel Klevit, using nuclear magnetic resonance imaging techniques, has been focusing its investigations on the N terminus. ...

Magnetic resonance angiography in clinical medicine

...pplied. With the invention of non-invasie magnetic resonance imaging (MRI) technique, imaging of flow has blossomed into a powerful technique to visualise blood flow in vessel, called MR Angiography (MRA). Blood vessels are rendered, not in the usual tomographic format of standard MR images, but as a projecti...

New technique to diagnose heart disease

...oblems. A new method of scanning based on magnetic resonance imaging is proving to be a useful alternative to c...sity of Cleavland have learned that using magnetic resonance imaging (MRI) gives results that are equally effective. They looked at 80 patients, in the US and ...

Computers may become surgeons

...eless. And although the small number of magnetic resonance imaging machines worldwide are capable of providing updated images during surgery, the instruments still have to be held and manipulated by humans. The researchers believe their work could have a significant impact on the emerging field of image-guid...

Cleft lip and palate are due to abnormality in brain structure

...le control subjects, the researchers used magnetic resonance imaging to study brain volume and tissue composition. They found that the volume of the anterior portion of the cerebrum was enlarged in men with clefting and that this enlargement is inversely associated with Full Scale IQ, which measures verbal and...

Tamoxifen does not adversely affect the brain

...ive decline. The researchers used proton magnetic resonance spectroscopy to determine levels of the cerebral metabolite myo-inositol, which has been found at elevated levels during brain injury, in the brains of 80 women. Sixteen of the women were breast cancer patients who had received tamoxifen therapy for ...

New operation for kidney cancer

...al cryosurgery. //The procedure relies on magnetic resonance imaging to guide a surgical probe while removing cancerous tissue. So high-tech is this procedure, that the surgeon could demonstrate his 60 operation to a group of colleagues in Italy using telemedicine. The team now reports on progress among the ...

Music training and Ginkgo biloba benefit memory

...esults of a 1995 study that compared MRI (magnetic resonance imaging) scans of the brains of musicians with non-musicians. The MRIs showed that the left planum temporale region of the brain is larger in musicians than in non-musicians. If this [difference] results from a change in cortical organization, the le...

Some more sensitive to pain

... their study, Coghill and colleagues used magnetic resonance imaging to assess brain function. They found that the brain regions important in registering pain lit up in those participants who said a heat stimulus was intensely painful. But those who said that the same stimulus was only mildly painful had minim...

Meditation Works Medically

...d future studies be done using functional magnetic resonance imaging technology to look more closely at the effects of mindful meditation. They also suggest future research look into the biological consequences of this type of approach....

Pain of Denial Compared to Physical Pain

...ctivities were monitored using functional magnetic resonance imaging. Though the figures were computer-generated, students believed the figures were linked to other student players not in the room. During the first round of Cyberball, students were limited to only watching the game. During round two, their pl...

Link Between Alcohol and Decrease in Brain Size

...women, age 55 and older. Researchers used magnetic resonance imaging// to determine their brain size, infarcts and white matter lesions, which are changes in the brain correlated with the risk of stroke and to study if a link existed between low to moderate alcohol consumption and a decrease in brain size of m...

Urine Test for Kidney Cancer

...ethods to diagnose the disease, including magnetic resonance imaging, computed tomography scans, ultrasounds, and, ultimately, biopsy. Since diagnosis is difficult, about 25 percent to 40 percent of people who are diagnosed with the disease are already in an advanced stage. However, the cancer is often curable...

New Technique to Study Infants Brain.

...birth. Researchers are using functional magnetic resonance imaging, or fMRI, to study infant brain activity in response to speech. They say this is the first time fMRI has been used to study infants. It is a noninvasive way to study neuronal responses, and the doctors say it does not use radiation or pharmac...

Brain Infarctions Found In Patients Suffering From Migraine

...ed in the study. Participants had a brain magnetic resonance imaging, blood samples drawn, and a physical and neurological examination. Their examinations were conducted during migraine-free periods. Researchers did not find a significant difference between patients with migraines and the control groups in o...

The Reason For Depression in Adolescents

... diagnosed with major depressive disorder.Magnetic resonance imaging was performed to measure the volume of each teen’s left and right hippocampus. The results indicated that the hippocampus of patients with depression was, on average, 17 percent smaller than those without mental illness. The study also foun...
