Molecular Imaging

Nuclear imaging, also called molecular imaging, includes positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. This section includes radiopharmaceuticals and tracers, PET-CT, SPECT-CT, and PET-MRI. Molecular imaging includes the field of nuclear medicine, which uses very small amounts of radioactive materials, or radiopharmaceuticals, to diagnose and treat disease.

The patient had failed multiple standard therapeutic maneuvers before presenting for 18F-FDG PET/MR imaging.

Adult male with decades of right neck pain, discomfort and tightening following birth injury. The patient had failed multiple standard therapeutic maneuvers before presenting for 18F-FDG PET/MR imaging. Images shows abnormally elevated FDG uptake (white arrows; SUVmax = 1.2) observed in a linear pattern in the space in the posterolateral right neck, between the oblique capitis inferior and the semispinalis capitis muscles, where the greater occipital nerve resides. By comparison, the same region on the contralateral, asymptomatic side of the neck has an SUVmax = 0.7. This result encouraged a surgeon to explore the area. The surgeon ultimately found a collection of small arteries wrapped around the nerve in this location. The small arteries underwent lysis by the surgeon and the patient reported tremendous relief of symptoms. (A) Coronal thick slab MIP of 18F-FDG PET.
