assessment, whereas CMR-with better spatial resolution than MDCT-in the myocardial viability. 2 In contrast to the methods that focus on cardiac anatomy listed above, the imaging tools used in nuclear cardiology are mostly dedicated to the functional assessment based on the uptake of radioisotopes by the cardiac structures. This enables to evaluate the myocardial perfusion, metabolism and viability, adrenergic innervation, radionuclide ventriculography, and intracardiac leakage (both left -to-right and right -toleft). Although nuclear cardiology methods are acknowledged and recommended by experts in the European Society of Cardiology (ESC) guidelines, 3,4 its clinical value seems to be still underpowered most probably by limited availability

Complex Regional Pain Syndrome (CRPS) is a neurological disorder of unknown etiology which may lead to severe disability. Its diagnosis is very difficult and based on diagnostic criteria which have been changing over last years. Still, there is no golden standard in diagnosis of this entity. Three-phase bone scan is a widely used diagnostic modality which has been proved useful in CRPS evaluation. The syndrome may present various scintigraphic patterns. Different diagnostic modalities can also be helpful when CRPS is suspected including plain film radiography, magnetic resonance imaging and ultrasonography. Multidisciplinary approach is necessary for proper and quick diagnosis. We present a case of CRPS in 12-year-old girl in whom the diagnosis was based on the bone scan.

SPECT/CT imaging provides detailed information on the radiotracer distribution and enables simultaneous lesion morphology evaluation.This hybrid imaging delivers complementary information about patient's disease.We present two cases in which SPECT/CT imaging and cooperation between the nuclear medicine physician and radiologist quickly clarified the diagnosis, sparing patient unnecessary diagnostic procedures or treatment.

A 33-year-old male was admitted to local Nuclear Medicine Department with suspected femoral head necrosis. His chief complaint was pain located in left inguinal region exacerbating during walking. He was forced to use a crutch.Three-phase bone scan (TPBS) was performed according to the standard protocol used in our Department.
