Ga DOTATATE PET/CT performed better than F-FDG PET/CT and is useful in the detection of tumors causing oncogenic osteomalacia. Therefore, in clinically suspected cases of hypophosphatemic osteomalacia, Ga DOTATATE PET/CT may be performed as first-line imaging investigation to avoid delay in the treatment of this devastating but curable disease. However, further studies with large patient population are warranted to validate our data.

Consistent and significant myocardial FDG uptake suppression is possible in most patients using LCHFPP diet. The LCHFPP diet, if taken as per protocol, leads to consistent myocardial FDG uptake suppression to allow for adequate evaluation of the left coronary artery inflammation in nearly all the patients. LCHFPP diet is also significantly more efficacious than prolonged (>12 hours) fasting protocol in suppressing myocardial FDG uptake.

One-third of all NCS in India is due to BA and among the intrahepatic causes acquired infection and galactosaemia are common. Liver biopsy is the best method to differentiate NH from BA.

F-FDG-LL PET/CT has high specificity for the diagnosis of DFO in complicated diabetic foot. The F-fluoride PET/CT helps in the characterization the extent of underlying CN. An early and accurate diagnosis with F-FDG-LL PET/CT aids the rational initiation of antibiotics for DFO.
