To compare the diagnostic interpretation of traditional ventilation/perfusion (V/Q) planar images with that of planar-like images reprojected from single-photon emission computed tomography (SPECT) data sets. ⋯ We have shown that the performance of reprojected planars from SPECT V/Q was similar to that of traditional planars. These results have potential important implications for patient workflow in busy nuclear medicine departments, as well as for patient comfort.

The aim of the study was to clarify the clinical significance of single-photon emission computed tomography/computed tomography (SPECT/CT) imaging in terms of technetium-99m galactosyl human serum albumin (99mTc-GSA) scintigraphy. To this end, we examined the relationship using data from surgical records of 67 patients with hepatocellular carcinoma who underwent hepatectomy. ⋯ Under the ICGR15 test as the standard for preoperative hepatic function, auxiliary application of LHL15 and functional volumetry provides useful information on hepatocellular carcinoma patients undergoing hepatectomy.

The aim of this study was to evaluate the clinical utility of (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography-computed tomography (PET-CT) in staging and restaging of patients with malignant primary salivary gland tumours. ⋯ (18)F-FDG PET-CT shows high accuracy in staging and restaging of patients with malignant primary salivary gland tumours. It is more specific than CIM for this purpose.

The aims of this study were to evaluate the ability of [F]fluorodeoxyglucose (F-FDG)-PET/computed tomography (CT) to identify tumor recurrence, nodal metastases, and distant metastases for surveillance and discuss the optimal timing of F-FDG-PET/CT examination after the completion of treatment for head and neck malignancy. ⋯ F-FDG-PET should be performed immediately for patients with clinically suspected recurrent disease. In others, it should be performed at later than 2 months after the completion of the treatment.
