A 69-year-old woman visited our hospital with a 2-month history of general fatigue, high fever, and dyspnea. Physical examination showed no abnormalities in superficial lymph nodes or respiratory sound. A chest computed tomography scan showed diffuse mild ground-glass attenuation in bilateral lung fields, whereas FDG-PET revealed intense uptake of FDG throughout the lung.

A 68-year-old woman was referred for a nodule in the right lung and hilar and mediastinal lymphadenopathy. Physical examination revealed left cervical lymphadenopathy. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) images revealed radiotracer uptake in the pulmonary nodule and multiple lymph nodes of the truncus. Biopsies confirmed the diagnosis of synchronous diffuse large B-cel...

This report presents a case of 49-year-old woman with complaint sore throat and front neck pain, who referred to hospital for thyroid scan due suppressed TSH level (0.005 mU/L). Diffuse bilateral lungs uptake in the was noticed incidentally. The patient had positive history COVID-19 symptoms. Multifocal ground-glass opacities (GGOs) both were compatible typical features lung involvement COVID-1...

A 62-y-old woman was found to have a lung mass and a brain mass. The brain mass was resected, and the histopathologic findings were suggestive of a gastrointestinal primary tumor with neuroendocrine features. She was referred for an 111In-octreotide SPECT/CT scan to evaluate for somatostatin-avid disease. After injection of 222 MBq (6 mCi) of 111In-octreotide, planar SPECT images (Fig. 1A) and ...

Interstitial lung disease (ILD) frequently accompanies polymyositis (PM) and dermatomyositis (DM) and is a major cause of mortality. The rapid diagnosis of ILD is paramount. However, the early changes of presymptomatic ILD are difficult to detect. We present a patient with DM who had positive uptake in the lung of FDG-PET/CT as well as 'mechanic's hands' appearance, increased serum ferritin and...

STUDY OBJECTIVES To determine whether acute changes in shielded lungs can be detected by positron emission tomography (PET) after radiation therapy. DESIGN Retrospective cohort study. SETTING University-affiliated medical center. PATIENTS Sixteen patients undergoing radiation therapy for lung cancer who had PET scans after receiving treatment. INTERVENTIONS None. MEASUREMENTS AND RESU...

A 31-year-old woman who had multiple orthopedic surgeries on the left lower limb and recently suffered from pain redness in lateral thigh was referred to hospital rule out osteomyelitis by [ 99m Tc]UBI scintigraphy. Except soft tissue inflammation mentioned region, scan showed significant diffuse both lungs uptake incidentally. The patient experienced symptoms of COVID-19 disease recently. Ches...

OBJECTIVES This study aimed to investigate the association of diffuse splenic F-18 fluorodeoxyglucose (FDG) uptake on positron emission tomography/computed tomography (PET/CT) with tumor maximum standardized uptake value (SUVmax), presence of distant metastases, and hematological and inflammatory parameters. MATERIAL AND METHODS Initial FDG PET/CT of 15 lung cancer patients with diffuse splen...

Extraosseous accumulation of technetium-99m-methyl diphosphonate (99mTc-MDP) on bone scan is not common. This phenomenon is often attributed to abnormality of calcium metabolism and has been reported in a variety of conditions including metabolic diseases and malignancies. A five years old boy is presented here, who was admitted to the pediatric emergency suffering from fatigue, respiratory sym...
