ABSTRAK
Perkembangan CT scan generasi multislice yang begitu pesat membuat pemeriksaan CT angiografi coroner sering dilaksanakan, akan tetapi pemberian informasi tentang dosis yang di terima pasien masih jarang dilakukan. Sehingga perlu dilakukan estimasi dosis pasien pada pemeriksaan CT angiografi coroner untuk mengetahui nilai dosis yang diterima oleh organ-organ yang sensitive terhadap radiasi seperti esophagus, paru-paru, payudara (pada wanita) dan jantung. Estimasi dosis dilakukan menggunakan program imPACT® dengan nilai nCTDIw didapat dari hasil pengukuran mengunakan detector pencil ion chamber menggunakan phantom acrilic 32 cm. Dari hasil estimasi di dapat dosis ekivalen yang diterima jantung 110 mSv ? 140 mSv, dosis efektif esophagus (thymus) 2,9 mSv ? 5.7 mSv, dosis efektif paru-paru 10 mSv -14 mSv, dosis efektif payudara 10 mSv ? 13 mSv dan total dosis efektif berkisar antara 31 mSv ? 42 mSv. Mengingat nilai total dosis efektif yang diterima pasien cukup tinggi, maka pasien CT angiografi coroner harus mendapatkan justifikasi yang kuat.
ABSTRACT
The Fast development of CT generation makes CT angiography coroner examination more frequence to be done, but the dose information of patient is rarely to be done. So it require to make patient dose estimation on CT angiography coroner examination. In order to know the dose receive by sensitive organ set of oesophagus, lung, brest and heart. Dose estimation is done using imPACT® program, using CTDI value obtain measurement using acrylic phantom with 32 cm diameter. From dose calculation the dose equivalent by heart is between 110 mSv - 140 mSv, and effective dose for oesophagus 2.9 mSv ? 5.7 mSv, lung 10 mSv ? 14 mSv and total effective dose between 31 mSv ? 42 mSv. Because effective dose receive by patient is very high, the CT angiography coroner patient must have a very strong justification.

Abstrak :
Written by internationally eminent experts in cardiovascular imaging, this volume provides state-of-the-art information on the use of MRI and CT in the assessment of cardiac and vascular diseases. This third edition, now in four-color, reflects recent significant advances in cardiovascular MRI technology and the continuing emergence of multi-detector CT as an important diagnostic modality, particularly for ischemic heart disease. Seven new chapters have been added including chapters on anatomy, cardiovascular MR in infants/​children, assessing myocardial viability, risk assessment in ischemic heart disease and MR guidance.
