*6.1.4 PET (positron emission tomography) rubidium*

PET rubidium has a 91% sensitivity and 89% specificity and produces less irradiation exposure, better quality of images, a greater degree of diagnosis, reduces invasive examination, and low cardiac death rates in obesity [47].

Therefore, PET rubidium is the nuclear imaging technique of choice for patients with obesity.

#### *6.1.5 Stress cardiac MRI (magnetic resonance imaging)*

Stress cardiac MRI and PET are likely the diagnostic techniques least affected by obesity.

The presence of ischemia predicted adverse events at 5 years of follow-up, regardless of whether scar was present. Lack of inducible ischemia is associated with a low annual major adverse coronary events (MACEs) rate of 0.3% at 2 years in patients with obesity [48].
