[ 1 ] - Radiation induced myocardial perfusion abnormalities in patients with left breast cancer: A prospective study with short and long term follow up
Introduction:The external beam radiation therapy for patients with left breast cancer at the mastectomy site may cause myocardial perfusion abnormalities. We intended to study the change of these abnormalities at short and long term post radiotherapy follow up. Methods: Twenty patients with left and 20 patients with right breast cancer comprised the exposed an...
[ 2 ] - Factors influencing the pattern and intensity of myocardial 18F-FDG uptake in oncologic PET-CT imaging
Introduction:Myocardial 18F-FDG uptake is highly variable in oncologic whole body 18F-FDG PET/CT studies, ranging from quite intense to minimal distribution. Intense or heterogeneous myocardial 18F-FDG uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardiu...
[ 3 ] - Development of 153Sm/177Lu-EDTMP as a possible therapeutic complex
Introduction:Targeted radionuclide therapy (TRT) has been demonstrated to be an effective therapeutic tool in patients with disseminated bone metastasis. TRT is generally performed with a single radionuclide. In this study we investigated the feasibility of combined TRT with a high-energy beta emitter (153Sm) and a low energy beta emitter (177Lu) in wistar...
[ 4 ] - How to manage patients with undetectable thyroglobulin but thyroid residue after radioiodine ablative therapy in differentiated thyroid carcinoma, retreatment or observation?
Introduction:Differentiated thyroid carcinoma (DTC) follow-up after thyroidectomy and radioiodine-ablation is performed mainly by thyroglobulin (Tg), diagnostic iodine-131 whole body scan (DxWBS) and sonography. Some patients with undetectable Tg have thyroid-bed uptake after ablation in whom decision making regarding the need for retreatment is still controversial. Me...
[ 5 ] - Sentinel lymph node biopsy correctly predicts regional lymph node recurrence in trunk malignant melanoma with multiple drainage basins
We report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (SLN) biopsy. Four peritumoral intradermal Tc-99m phytate injection was performed and SLNs were detected in both axillary and right inguinal regions. On the biopsy only the right axillary SLN was metastatic leading to right axilla...
[ 6 ] - Effectiveness and complications of 153Sm-EDTMP in palliative treatment of diffuse skeletal metastases
Introduction: The aim of the present study was to evaluate the efficacy and safety profile of bone palliative therapy following administration of 153Sm-EDTMP in patients with intractable metastatic bone pain. Methods: Sixteen patients (9 male, 7 female) aged 29-80 years (57.3±16.7 years) with severe metastasis-related bone pain resistant to analgesic medications were enrolled in the...
[ 7 ] - Evaluation of myocardial perfusion and function after kidney transplantation by Gated SPECT myocardial perfusion scintigraphy
Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
