PURPOSE: Non-small cell lung cancer (NSCLC) patient radiation therapy (RT) is planned without consideration of spatial heterogeneity in lung function or tumor response. We assessed the dosimetric and clinical feasibility of functional lung avoidance and response-adaptive escalation (FLARE) RT to reduce dose to [(99m) Tc]MAA-SPECT/CT perfused lung while redistributing an escalated boost dose within [(18) F]FDG-PET/CT-defined biological target volumes (BTV). METHODS: Eight stage IIB-IIIB NSCLC patients underwent FDG-PET/CT and MAA-SPECT/CT treatment planning scans...

AIM: The use of positron emission tomography (PET/CT) in kidney tumors has increased greatly in recent years. There have been few studies on the effect of SUVmax values detected by PET/CT on the mortality and survival estimation in patients with kidney tumors. In this study, it is hoped to contribute to the literature of research on survival and mortality estimations of kidney tumour patients through an evaluation of SUVmax values measured with PET/CT scan. MATERIAL AND METHODS: A retrospective review was made of the files of 21 patients newly-diagnosed with kidney tumor and with disease staging determined with PET/CT in the Nuclear medicine Department of Saglik Bilimleri University Diyarbakir Gazi Yasargil Training and Research Hospital between August 2007 and April 2012...

BACKGROUND: Nasopharyngeal carcinoma (NPC) is a special subtype of head and neck cancer (HNC). At present, there are no highly specific prognostic markers to aid in tumor grading and guide patient treatment modalities for NPC. The prognostic value of pretreatment F-fluorodeoxyglucose positron emission tomography-computed tomography (F-PET-CT) in NPC patients is controversial and no consensus exists as to its predictive capability. METHODS: To analyze the predictive efficacy of F-PET-CT imaging in NPC patients, data from MEDLINE, EMBASE, the Cochrane library, CBM, CNKI, and VIP (inception to July 2016) were accessed...

Lithium intoxication is known to induce cognitive deficits along with motor and behavioral changes, even in association with normal serum levels. However, cases with comprehensive neuropsychological assessment of the deficits are rare. In our patient, we initially found severe cognitive deficits, including apraxia and visuo-constructive problems, and temporo-parietal FDG-PET hypometabolism. Neuropsychological and imaging findings were highly suggestive of Alzheimer's disease. However, lithium intoxication was suspected to account for these findings because of a Parkinson's syndrome, despite serum levels being in the upper therapeutic range...

Prolymhocytic leukemia (PLL) is a rare subtype of lymphocytic leukemias and its cells are immature lymphocytes. It is divided into 2 subgroups: T-PLL and B-PLL according to the lymphocytic origin of the cells. Discriminating B-PLL from other diseases with clinically-similar features is important because of the different treatment approaches and follow-up programs. Hereby, we report a 80-year-old woman presenting with fatigue, leucocytosis and mild anemia. Her peripheral blood smear evaluation revealed 85% prolymphocytes with moderately condensed nuclear chromatin, prominent nucleoli, and a faintly basophilic cytoplasm...

Neuroendocrine tumors (NET) are often metastatic at the time of diagnosis. Metastatic well-differentiated (G1/G2) NET may display a wide range of behaviors, ranging from indolent to aggressive, even within apparently homogeneous categories. Thus, selecting the optimal treatment strategy is a challenging task. Somatostatin receptor imaging (SRI) is the standard molecular imaging technique for well-differentiated NET. When performed with (68)Ga-labeled somatostatin analogs (SRI-PET), it offers exquisite sensitivity for disease staging...

Background: PET scans using FDG and somatostatin receptor imaging agents have both been used to study neuroendocrine tumours. Most reports have documented the sensitivity and specificity of each radiopharmaceutical independently, and even suggested the superiority of one over the other for different grades of disease. Aim: The aim of this work was to develop a grading scheme that describes the joint results of both the FDG and somatostatin receptor imaging PET scans in staging subjects with neuroendocrine tumours in a single combined parameter...

INTRODUCTION: (18)F-5-fluoro-N-(2-(Diethylamino)ethyl)picolinamide ((18)F-5-FPN) is a new positron-emission tomography (PET) radiopharmaceutical with potential for the detection of lymph node (LN) and pulmonary metastatic lesions of melanoma. We compared its performance with that of (18)F-deoxyglucose ((18)F-FDG). METHODS: Cervical LN and lung melanoma metastasis models were established in C57BL/6 mice. Primary tumors were created by injection of melanoma cells into the pinna, and the resulting cervical LN metastases were evaluated...

INTRODUCTION: Given that surgical treatment of refractory mesial temporal lobe epilepsy may cause memory impairment, determining which patients are eligible for surgery is essential. However, there is little agreement on which presurgical memory assessment methods are best able to predict memory outcome after surgery and identify those patients with a greater risk of surgery-induced memory decline. OBJECTIVE: We conducted a systematic literature review to determine which presurgical memory assessment methods best predict memory outcome...

BACKGROUND: Accurate quantification of PET studies depends on the spatial resolution of the PET data. The commonly limited PET resolution results in partial volume effects (PVE). Iterative deconvolution methods (IDM) have been proposed as a means to correct for PVE. IDM improves spatial resolution of PET studies without the need for structural information (e.g. MR scans). On the other hand, deconvolution also increases noise, which results in lower signal-to-noise ratios (SNR). The aim of this study was to implement IDM in combination with HighlY constrained back-PRojection (HYPR) denoising to mitigate poor SNR properties of conventional IDM...
