WebOct 3, 2024 · The effective dose for most SPECT scans, excluding cardiac stress/rest studies, is usually below 10 mSv. By comparison, the effective radiation doses for head computed tomography, chest computed tomography, and computed tomography coronary angiography are 2.0, 7.0, and 16.0 mSv, respectively. WebThe radiation dose delivered by CT is a major issue in this regard, because diagnostic CT can increase the overall radiation dose by up to 14 mSv ( 11 ). Low-dose CT is associated …
