P Parra-Díaz, N García-Casares
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: This study assessed whether primary tumor maximum standardized uptake value (pSUVmax) measured by (18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) could improve the prediction of axillary lymph node (ALN) metastasis in invasive ductal breast cancer (IDC). METHODS: In this study, 128 IDC patients who underwent pretreatment (18)F-FDG PET/CT and surgical resection of primary tumor with sentinel lymph node biopsy, ALN dissection, or both were analyzed...

Surgical resection of metastases represents an integral part of curative management in patients with testicular germ cell tumors (GCT). Primary nerve-sparing retroperitoneal lymph node dissection (nsRPLND) for low volume metastases in clinical stages I-IIB has to be differentiated from the more complex and more extensive postchemotherapeutic procedures. In Europe, primary nerve-sparing retroperitoneal lymph node dissection (nsRPLND) for clinical stage I nonseminomatous GCT (NSGCT) plays a subordinate. In clinical stage IIA/B, nsRPLND is indicated for patients with marker-negative metastases in whom cure rates of about 65% can be achieved with surgery alone...

18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET) and diffusion weighted magnetic resonance imaging with background signal suppression (DWIBS) are two powerful functional imaging modalities in the evaluation of the malignant plasma cell (PC) disease multiple myeloma (MM). Preliminary observations have suggested that MM patients with extensive disease according to DWIBS may be reported as being disease-free on FDG-PET ("PET-false-negative"). The aim of this study was to describe the proportion of PET-false-negativity in a representative set of 227 newly diagnosed MM patients with simultaneous assessment of FDG-PET and DWIBS, and to identify tumor-intrinsic features associated with this pattern...

BACKGROUND: Hybrid PET/MRI allows the acquisition of both fluorine-18-fluorodeoxyglucose (F-FDG) PET and cardiac magnetic resonance (CMR) during one session. Whether this will result in different referral to coronary revascularization (CR) is unknown. We compared this new hybrid method with all-nuclear/all-CMR methods in the assessment of viable myocardium and in downstream referral to CR. PATIENTS AND METHODS: Overall, 12 patients with rest perfusion defects on a single photon emission computed tomography (SPECT) were recruited for cardiac viability assessment using a PET/MRI device...

BACKGROUND: Texture features are being increasingly evaluated in (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) as adjunctive imaging biomarkers in a number of different cancers. Whilst studies have reported repeatability between scans, there have been no studies that have specifically investigated the effect that the time of acquisition post-injection of (18)F-FDG has on texture features. The aim of this study was to investigate if texture features change between scans performed at different time points post-injection...

The patient was a 79-year-old woman who had received enucleation of right pulmonary papilloma 7 years earlier. She experienced bloody sputum and was therefore referred to our hospital. Chest computed tomography revealed a mass shadow(21 mm) in the right upper lobe (S2). By bronchoscopy, there was no bulging lesion in the visible range. SCC and CEA increased to 6.4 ng/ml and 6.42 ng/ml, respectively. Whole-body 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased FDG uptake in the region of the right-lung mass shadow (maximum standardized uptake value 12...

(18)F-fluorodeoxyglucose PET/CT ((18)F-FDG-PET/CT) is widely applied in oncology for disease staging, assessment of therapy response, relapse diagnosis, follow-up and target volume delineation. In particular, it can detect early response during chemoradiotherapy (interim) because functional modifications usually precede morphological ones. This ability is crucial to the radiation oncologist for the management of patients, to avoid persisting with ineffective therapy - often leading toxicity - and to shift to potentially more effective alternatives...

Neuroendocrine tumours are extremely heterogeneous malignancies. Despite marked heterogeneity in clinical course and prognosis, few biomarkers exist to help predict prognosis and guide treatment. Many tumour-based biomarkers (Ki-67, mitotic count, genetic/epigenetic changes and microRNAs) exist, but only Ki-67 and mitotic count have strong evidence to support their routine use. Blood-based markers are easily repeatable, but currently established biomarkers (chromogranin A and urinary 5-HIAA) are difficult to measure accurately in practice...

Cancer cell metastasis is responsible for most cancer deaths. Non-invasive in vivo cancer cell tracking in spontaneously metastasizing tumor models still poses a challenge requiring highest sensitivity and excellent contrast. The goal of this study was to evaluate if the recently introduced PET radiotracer [(18)F]tetrafluoroborate ([(18)F]BF4(-)) is useful for sensitive and specific metastasis detection in an orthotopic xenograft breast cancer model expressing the human sodium iodide symporter (NIS) as a reporter...

In the context of delayed autoimmune encephalitis antibody results, functional imaging can support the diagnosis of limbic encephalitis associated with anti-voltage-gated potassium channel complex (VGKCC) antibodies. Here we present a typical case of VGKCC encephalitis in a 69-year-old woman whose symptoms responded to plasmapheresis. A cerebral 18F-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) scan performed prior to commencing treatment revealed striatal hypermetabolism assessed qualitatively and semi-quantitatively, with normal uptake in the cortex and cerebellum when analysed semi-quantitatively...
