Estimation the Doses of Patients Resulting from Diagnostic Cardiac Imaging Modalities

Shaban Alramlawy* and I Maamoun

Evaluating the hazards and beneficiary of cardiac imaging for patients is considered of high concern. There is a lack of information about the harm associated with cardiac modalities.

Aim: Comparison of different cardiac imaging modalities in terms of patient dose.

Method: 120 patients (weight=85 ± 10 Kg and Age=50 ± 10) are divided into three groups according to cardiac diagnostic procedures (A): n=40, SPECT (Siemens Symbia), Injected activity=950 MBq for stress/rest on two days); (B): n=40, Fluoroscopy (Siemens), The fluoroscopy average time and cine-modes was 4.2 ± 1.8 min and 10.7 ± 2.9 min respectively) and (C): n=40, CT Coronary (Philips 256), KV=120, MA=300).

Results: CT Coronary (Gp.C) is highly significant patient dose (p<0.005) than SPECT (Gp.A). Where the average effective doses of groups C and A are 32.0 ± 10.5 mSv and 13.5 ± 1.7 mSv respectively. The effective dose of ICA (Gp. B) is 49.1 ± 2.5 mSv which is highly significant (p<0.05) than A and C groups.

Conclusion: Our results concluded that there is evidence supportive of high effective dose which reflects an increased risk of cancer incidence at levels of radiation commonly received by cardiac diagnostic imaging modalities.
