Technetium 99m PSMA Superscan Mimicking a Bone Scan Gone Wrong.

Imaging of metastatic castrate-resistant prostate cancer to select patients suitable for peptide receptor radioligand therapy can be performed with both SPECT and PET PSMA radiotracers. Although PET radiotracers generally have higher sensitivity and spatial resolution, SPECT tracers can be an effective alternative when PET/CT systems are unavailable in the clinical setting. We present a case of a 43-year-old male, who was referred to our facility for workup for radioligand PSMA therapy.
