What is generally advised for the imaging prep for patients diagnosed with type 2 diabetes?

For patients diagnosed with type 2 diabetes, it is generally advised to perform imaging procedures in the afternoon after a fasting period. This timing helps to stabilize blood glucose levels, making it easier to interpret the imaging results accurately. Imaging in the afternoon allows the patient to fast adequately in the morning and receive necessary medications, while also possibly leading to improved imaging quality due to less fluctuation in glucose levels.

Fasting is important in PET imaging, as the elevated blood glucose levels can interfere with the uptake of radiotracers, leading to artifacts or decreased sensitivity in detecting abnormal tissue. By scheduling the imaging for the afternoon, healthcare providers can ensure that the patient is adequately prepared while balancing their diabetes management and overall health. This approach maximizes the likelihood of obtaining clear and useful images during the PET scan.
