Objectives: The aim of this study was to compare F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/magnetic resonance (MR) (with and without diffusion-weighted imaging [DWI]) to F-FDG PET/computed tomography (CT), with regard to the assessment of nodal and extranodal involvement, in patients with Hodgkin lymphoma and non-Hodgkin lymphoma, without restriction to FDG-avid subytpes. Ma...

a 60-year-old patient with testicular seminoma was referred for f-18 fdg pet/ct study to evaluate recurrence. in addition to hypermetabolic cervical, mediastinal and hilar lymph node tumoral metastases, segmental intense fdg uptake along the lumbar spinal cord suggestive of tumoral metastasis was noted which quite an unusual presentation is.  at the time of pet study the patient was symptomless...

Background: Accurate preoperative detection of the invasive components ductal carcinoma in situ (DCIS) is essential for an appropriate treatment. 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scan, which can indicate metabolic activity and aggressiveness breast cancer, may be used as one predictors DCIS needle biopsy. Objectives: To determine whether FDG...

BACKGROUND In myotonic dystrophy type 1 (DM1), only one FDG-PET study used statistical parametric mapping (SPM) showing frontal reduced FDG-uptake. Our aim was to 1) identify the FDG-PET area with the most severe reduced FDG-uptake using SPM8 in a larger group of patients 2) assess potential correlation between CTG-numbers and FDG-PET. METHODS FDG-PET was performed in 24 patients and compared...

Objective(s): Acute pyelonephritis presents with high-grade fever, dysuria, flank pain, leukocytosis, and microscopic hematuria. Urine culture aids in the diagnosis of this infection. It can be complicated or uncomplicated. Complicated pyelonephritis includes uncontrolled diabetes, transplant, pregnancy, acute or chronic renal failure, structural abnormality of the uri...

Primary pulmonary amyloidosis is an uncommon manifestation, characterized by amyloid deposition in the lungs and other associated tissue. The clinical presentation of amyloidosis is variable, with non-specific symptoms. The current study reports the case of a 59-year-old female presenting with primary pulmonary amyloidosis, indistinguishable from lung malignancy based on 18F-fluoro-deoxyglucose...

Objective: The existing literature of 18 F-FDG PET/CT in Ewing sarcoma investigates mixed populations of patients with both soft tissue and bone primary tumors. The aim of our study was to evaluate whether the maximum standardized uptake value (SUVmax) obtained with 18F-FDG PET/CT before and after induction chemotherapy can be used as an indicator of survival in patients with Ewing sarcoma orig...

we report a case of a 75-year old man that came at hematologist’s attention for lymphoma evaluation due to axillary lymph node enlargement and fever. thorax, abdomen and pelvis contrast-enhanced computed tomography (cect) showed lymph nodes, spleen and liver lesions. axillary lymph node biopsy was performed and the diagnosis of marginal zone lymphoma (mzl) at stage iv was postulated, then the p...

Diagnosing bone infection in its acute early stage is of utmost clinical importance as the failure to do so results in a therapeutically recalcitrant chronic infection that can only be resolved with extensive surgical intervention, the end result often being a structurally unstable defect requiring reconstructive procedures. [(18)F]-FDG-PET has been extensively investigated for this purpose, bu...

The purpose of this study was to evaluate prediction of prognosis after first-line radioimmunotherapy (RIT) of advanced follicular non-Hodgkin lymphoma (FL), by imaging with fluorine-18-fluorodeoxyglucose positron emission tomography with computed tomography (18F-FDG-PET/CT) three months after induction treatment by Iodine-131-rituximab (131I-rituximab). Objective response was determined using ...
