Early detection of radiation-induced heart disease using 99mTc-MIBI SPECT gated myocardial perfusion imaging in patients with oesophageal cancer during radiotherapy

Radiotherapy for EC induces cardiac damage from an early stage. 99mTc-MIBI SPECT GMPI can detect the occurrence of cardiac impairment during RT. The WM, WT, EDP and ESP may be valuable as early indicators of RIHD. The percentage of the heart volume that receives a high dose is an important factor that is correlated with RIHD.
