Summary

To explore the value of 18F-fluorodeoxyglucose (FDG) PET/CT imaging in early diagnosis of treatment-related cardiotoxicity (TACT) of lymphoma using visual method and semi-quantitative method.

Detailed description

First of all, the cardiac 18F-FDG uptake in patients with lymphoma will be observed by visual method: according to the uptake site, it will be divided into left ventricular uptake and biventricular uptake, and according to the degree of uptake, it will be divided into equal uptake (myocardial uptake is lower than cardiac blood pool uptake), moderate uptake (myocardial uptake is between cardiac blood pool uptake and liver uptake) and high uptake (myocardial uptake is higher than liver uptake). According to the uptake pattern, it can be divided into diffuse and segmental uptake.Then,using the region of interest method to mesure the value of myocardial uptake of 18F-FDG.The difference value of heart's SUVmax (Δ SUVmax- heart) and% Δ SUVmax- heart before and after chemotherapy or immunotherapy will be calculated. And SUVmax- heart / SUVmax- mediastinum ratio, SUVmax- heart / SUVmax- liver ratio and SUVmax- heart / SUVmax- background ratio (left gluteal muscle) after treatment. Taking the abnormality of ECG (early TACT) as the end point.
