CTD was introduced to observe subendocardial myocardial VG at baseline , during ischemia and with DOB infusion.
以CTD观察心内膜下心肌缺血及应用DOB后心内膜下心肌的VG变化.
PET slightly overestimate extent of necrosis myocardium and can't distinguish transmural necrosis from subendocardial necrosis.
pet高估心肌坏死范围,且不能判断心肌梗死的透壁程度.
