To investigate whether the evaluation of tumors, lymphoid cell-rich organs, and immune-related adverse events (IRAE) with F-FDG PET/CT can predict efficacy outcome immunotherapy.Forty patients who underwent F-FDG-PET/CT scans before after therapy immune checkpoint inhibitors from December 2013 to 2016 were retrospectively enrolled (malignant melanoma, n = 21; malignant lymphoma, 11; renal cell carcinoma, 8). SUVmax baseline first restaging evaluated in spleen, bone marrow, thyroid pituitary...
PET using radiolabeled prostate-specific membrane antigen (PSMA) is now being more widely adopted as a valuable tool to evaluate patients with prostate cancer (PC). Recently, 3 different criteria for interpretation of PSMA were published: the European Association Nuclear Medicine (EANM) criteria, Prostate Cancer Molecular Imaging Standardized Evaluation and Reporting Data System. We compared these in terms interreader, intrareader, intercriteria agreement. <b>Methods:</b> from 104...
We developed novel magnetic resonance enterocolonography (MREC) for simultaneously evaluating both small and large bowel lesions in patients with Crohn's disease (CD). The aim of this study was to evaluate the diagnostic performance MREC by comparing results procedure those endoscopies CD. Thirty established CD were prospectively examined newly MREC. Patients underwent ileocolonoscopy (ICS) (24 procedures) or double-balloon endoscopy (DBE) (10 after on same day. Two gastroenterologists two...
To evaluate the usefulness of change in automated bone scan index (aBSI) value derived from scintigraphy findings as an imaging biomarker for assessment treatment response and survival prediction metastatic castration-resistant prostate cancer (mCRPC) patients treated with Ra-223. This study was a retrospective investigation Japanese cohort 205 mCRPC who received Ra-223 14 hospitals between July 2016 August 2020 whom before after radium-223 available. Correlations aBSI change, changes serum...
The purpose of this study is to evaluate the usefulness dual-time-point 18F-FDG PET/CT for discriminating between benign and malignant salivary gland tumors.Dual-time-point FDG images 40 tumors (20 20 malignant) were evaluated retrospectively. maximum standardized uptake values (SUVmax) in early delayed phases retention index each tumor calculated compared by Mann-Whitney U test. Receiver operating characteristic (ROC) analysis was used determine diagnostic accuracy tumors. correlation...
The aim of this study was to assess the utility positron emission tomography/computed tomography (PET/CT) for investigation patients with suspected paraneoplastic neurologic syndrome (PNS).We reviewed whole-body fluorodeoxyglucose (FDG) PET/CT studies (ordered by neurology department) performed at our hospital between December 2005 and November 2010; 27 cases (16 men, 11 women; mean age, 65 years) who were having PNS selected.Of patients, 6 (22%) had an abnormal FDG uptake. Of these 5 (19%)...
The concept of cenesthopathy was first introduced by Dupré and Camus in 1907 to describe clinically unexplainable bodily sensations mainly attributed psychiatric pathology. If it occurs oral regions, is termed has been special interest psychiatrists dentists. While there no independently defined criteria for this condition, which classified as either a delusional or somatoform disorder, clinical practice research require standard scale measure rate its symptoms. In study, we included any...
Oral cenesthopathy is a somatic delusion or hallucination involving the oral area and categorized as delusional disorder, type. The pathophysiology of this intractable condition remains obscure. In study, we clarified by evaluating regional brain perfusion. We performed single photon emission computed tomography (SPECT) using (99m)Tc-ethylcysteinate dimer in 16 subjects (cenesthopathy:control = 8:8). SPECT images were visually assessed qualitatively, quantitative analyses also...
Abstract This study assessed the possibility of semi-automatic harmonization standardized uptake values (SUVs) in multicenter studies. Phantom data were acquired using 16 PET/CT scanners (including 3 with a silicon photomultiplier detector). PET images obtained 30-min/bed scans for optimum filter calculations and 90–180-s/bed SUV validation under clinical conditions obtained. Time flight reconstruction method point-spread function correction allowed. The optimal full width at half maximum...
Oral cenesthopathy is a somatic delusion in the oral area and categorized as delusional disorder, type. Patients experience unusual annoying sensations mouth such pulling on teeth, moving overly secreting mucus, tingling pain, so on, without base. The condition usually treatment-resistant impairs patients' quality of life. We report case successfully treated with modified electroconvulsive therapy, who demonstrated altered regional cerebral blood flow before after treatment detected by...
A significant number of patients visit dental clinics because unusual oral sensations for which no physical cause can be found. Such are recognized as having somatic delusion (OSD). OSD may either primary (monosymptomatic) or secondary to another disease, such depression cerebral infarction. Although the presenting complaints with and nearly indistinguishable, symptoms in seem resistant treatment compared those OSD. Moreover, right dominant blood flow (CBF) has been reported OSD, but...
