New point scale to ascertain the stroke recovery

...es of recovery. This new 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...

Bar Codes For Prescribed Drugs

...alth system has already moved to purchase bar code scanning systems, but is being hampered because most products still lack the codes. Such a proposal could be technically challenging, but potentially time-consuming and very expensive....

Dyslexia due to cerebellum abnormality

... of eight normal and eight dyslexic adults using a scanning technique called positron emission tomography (PET). patients were monitored as they performed a pre-learned sequence of right hand finger movements, and as they learned a new sequence of finger movements, also with their right hand. During the tas...

New technique to diagnose heart disease

...s used to diagnose heart problems. A new method of scanning based on magnetic resonance imaging is proving to be a useful alternative to conventional methods for diagnosing heart problems.//The usual technique for diagnosing blocked arteries that are the cause of heart disease involves injecting a dye into th...

Why cluster headaches?

...e physical structure of the brain. But using a new scanning technique, doctors have established that cluster headaches are likely to be caused by excessive growth of grey cells in one part of the brain. By using the latest imaging techniques, Professor Goadsby and colleagues found an increase of grey matter...

Why a headache?

By the use of novel scanning methods doctors have found that cluster headaches are due to excessive gray cells in the brain. It is the section that governs the body clock, which could be responsible for the regularity of the headaches' aspect.// Cluster headaches are marked by...

Scientists found ancient Human Germ Killer

...re appeared to be no comparable human defensin. By scanning the human genome, they found a place where the molecular sequences was nearly 90 percent identical to the monkey gene for RTD-1. However, inside the human gene was a mutation that prevented it from working, as if an extra, meaningless chain of lette...

Effect of Osteosarcoma predicted by scans

...have been studying about the outcome of the hitech scanning technologies recently. A scan that looks at glucose uptake in a tumour shows who has a poor prognosis. Osteosarcoma is a bone tumour which affects mainly younger people. //It's an unusual cancer and one where the outcome tends to be rather unpredicta...

Associated scan for detecting ovarian cancer spread

...dominal cavity. Positron emission tomography (PET) scanning is useful// for detecting the activity of tumour tissue, while computed tomography (CT) is good for imaging anatomical detail. Researchers at Johns Hopkins Medical School have found that combining the two detects ovarian cancer spread better than usi...

New virtual colonoscopy procedure for easier colon screening

...e been using. This procedure// allows computerized scanning of the colon which is more comfortable for the patient. The patient is made to lie down in a computerized tomography (CT) scanner while a small probe is inserted into the rectum so that the colon can be inflated with carbon dioxide gas. The CT scanne...

Head injury X-rays may actually be causing harm

... the head. The authors of the research say that CT scanning after minor head trauma now needs to be reconsidered. A team from the Karolinska Institute in Stockholm, with colleagues in Harvard and Athens, followed up more than 3,000 men who had been given radiation treatment for haemangioma, an excessive gro...

Radiation Exposure Found To Affect Intellect Later In Life
