With heart CT scan the cancer (the cancer) risk increase

　The report that was published to the American doctor periodical “JAMA” July 18th number cancer risk of the especially woman and the young person increases the CT crown artery contrast which decides the presence of heart obstacle (CTCA) with inspection. American Colombian University which leads research (New York) Andrew J. Doctor Einstein, has expressed that the doctor when choosing appropriate inspection method for the patient, it is the expectation where this knowledge is useful.

　The united states Scott & the White hospital (Texas state) as for Gregory Dehmer doctor, quite being useful by CT, although the picture which is superior it is obtained, as for the patient disclosing to abundant radiation it had already been informed, but as for this research you have expressed that it is something which verifies that. It is important for the doctor, the case where the blood vessel contrast due to CT is suited when it is to recognize the case which is not suited sufficiently the same person points out.

　The crown artery disease (CAD), the artery which supplies the blood to the heart hardens and in the disease which strangulates, in the United States both the man and woman has reached 1st rank of cause of the death. But as for the most standard diagnostics those due to crown artery contrast, because in this inspection it is necessary to insert the catheter into the blood vessel, heavily is serious times when the complication is caused there are, the inspection method whose invasive characteristic is low was required. It is CTCA where the one of them is approved in 2004. CTCA sensitivity and the degree of uniqueness can be high together inspect the presence of the disease quickly the urgent treatment room (ER) the chest which is conveyed painfully concerning the patient.

　But, the cancer risk due to this inspection was not so far quantized. In the latest research, the life cancer risk due to the radiation disclosure of 64 slices CTCA making use of computer simulation, was appraised. As a result, life cancer risk with 20 year old women had 3,261 1 and width with 1/143 and 80 year old men. But when ECTCM (the cure which makes the lighting quantity decrease with one section of heart period) with the method of saying is used, cancer risk respectively goes down to 5,017 1 with 1/219. Although always the choices which are optimum you cannot call CTCA for the young person and the woman for the patient of advanced age as for risk that much high thing became clear vis-a-vis the profit.

　As conclusion, is a chest painfully, the crown artery disease is really doubted is, kind of when, it is good making use of CTCA with the judgment of the doctor, but unless it is recommended, Einstein you express that CTCA is used easily with purpose of the mere medical examination.
