CT scan detects 'multiple conditions in single examination'

scanner

A new CT scan has been developed that can detect two separate coronary conditions in one procedure, according to a new report.

Researchers from Massachusetts General Hospital found that the scan could identify cases of myocardial ischemia and coronary arteries at the same time.

They studied data from 34 cardiac patients who were likely to require angiography via cardiac catheterisation, by taking three CT scans rather than using a SPECT stress perfusion study.

As well as achieving a similar level of accuracy to the SPECT test, the three CT scans did not exceed the radiation dosage that the nuclear technology would have used.

Dr Ricardo Cury, the study's principal investigator, said: "This is among the first demonstrations of the use of cardiac CT to detect both coronary artery stenosis and resulting myocardial ischemia simultaneously in a single examination."

A recent study showed that doctors can use validated prediction rules to decide when a child head trauma patient can have a CT scan carried out on them, because for some patients it can be unnecessary.
