Delayed diagnosis of parathyroid cancer manifested with pubic bone lesions and chronic kidney failure. Tricks and pitfalls of management.

Introduction: Parathyroid cancer (PTC) is an extremely rare malignancy with an incidence of 5.7 per 10 million people. The exact preoperative or intraoperative diagnosis is difficult, but of paramount importance, because resection with negative margins is the only effective treatment.

Discrepancies and priorities in staging and restaging malignant lymphoma by SPET, SPET/CT, PET/CT and PET/MRI.

Due to the rapid development of modern imaging methods and also of medical oncology, there has been a significant progress in diagnosis and treatment of malignant lymphomas in the last few years. Nuclear medicine (NM) imaging methods gained new perspectives via the so called hybrid technologies-single-photon emission tomography combined with computed tomography (SPET/CT), positron emission tomography combined with computed tomography (PET/CT) and recently even positron emission tomography combined with magnetic resonance imaging (PET/MRI), which have led to a better image quality and diagnostic findings. Since SPET/CT evolved later than the "gold standard" 18F-FDG-PET/CT in lymphoma diagnostics, there are fewer studies with it, but it seems to be an excellent alternative to PET/CT.

Scintimammography and single-photon emission computed tomography for postoperative image guidance for radiation treatment planning in breast cancer patients.

Purpose: To evaluate post-surgical tumor-metabolic regions outside of the computed tomography (CT)-defined volume for radiation therapy (RT) planning using functional imaging of scintimammography (SMG) ± single photon emission computerized tomography (SPECT) in breast cancer (BC) patients.

Methods: 62 operated high-risk BC females, mean age 50.45 years, underwent SMG±SPECT before RT planning.

Myocardial scintigraphy, echocardiography and proBNP for early detection of myocardial cardiotoxicity in breast cancer patients after chemo-radiotherapy.

The most severe side effect in breast cancer patients, treated with chemotherapy and/or radiotherapy is cardiotoxicity, leading to chronic heart failure and worsening the quality of life. The aim of our study was to detect early in these patients signs of cardiotoxicity. Twenty four breast cancer patients were included in our study after combined treatment (chemo and radiotherapy).

Impact of PET and CT in PET/CT studies for staging and evaluating treatment response in bone and soft tissue sarcomas.

Purpose: Study impact of F-18 FDG PET/CT on initial staging, restaging, and evaluating treatment response (ETR) in bone and soft tissue sarcomas (BSTS), focusing on discrepancy between CT and PET portions.

Patients And Methods: Ninety-three BSTS patients having 204 F-18 FDG PET/CT studies were retrospectively reviewed. They were divided into 4 groups.
