We present the bone scintigrams of two patients, which demonstrate diffuse extraosseous uptake of a bone agent in metastatic masses in the liver, one from a primary lung tumor and one from a primary breast tumor. The bone imaging agent did not localize in the brain metastases in these patients. CTs of the abdomen in both patients showed massive metastases in the liver with multiple areas of tum...

Increased metabolic activity in muscle secondary to excessive muscle activity during the uptake phase and shortly before FDG injection is a known phenomenon. We present FDG PET/CT findings in a young male, known case of carcinoma maxilla His scan showed diffuse increased metabolic activity in multiple skeletal muscle groups. There was history of unaccustomed, strenuous sports activity of skiing...

We report a case of miliary sarcoidosis with secondary Sjogren's in a 45-year-old male who presented with symptoms of sicca syndrome in the form of dryness of eyes and mouth with parotid swelling. Computed tomography thorax showed mediastinal and hilar lymphadenopathy, bilateral miliary opacities in lung parenchyma. Whole body FDG PET/CT showed involvement of both parotids, liver, diffuse uptak...

Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...

To analyze the specificity of the diffuse pattern of cardiac uptake with technetium-99m stannous pyrophosphate (TcPYP), we evaluated the bone scans of 1,383 noncardiac patients and the myocardial scintigrams of 120 cardiac patients. Seventy (14.4%) of 483 bone scans performed on a scintillation camera revealed diffuse TcPYP cardiac uptake. Among the total 603 camera bone scans and myocardial sc...

bilateral diffuse intense breast uptake was noted in a 40 year old female who was evaluated with tc-99m sestamibi (mibi) myocardial perfusion scan for possible ischemia. she was breast feeding her 1.5 year old child. the intense uptake in the breasts was superimposed on the apical and anteroapical regions of the myocardium and caused interpretation problem. we recommend considering tc-99m mibi ...

BACKGROUND (18)F-fluorodeoxyglucose (FDG) PET plays an important role in the detection of cardiac involvement sarcoidosis (CS). However, diffuse left ventricle (LV) wall uptake sometimes makes it difficult to distinguish between positive uptake and physiological uptake. The aims of this study were to evaluate the effects of 18-h fasting with low-carbohydrate diet (LCD) vs a minimum of 6-h fasti...

A discrete MIBI avid lung lesion was found in cinematic views of myocardial perfusion imaging (MPI) of a 59 year-old woman. Interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. MPI was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis.  She had no...

introduction: recombinant human thyroid-stimulating hormone(rhtsh) increases radioactive iodine uptake(raiu) in selected populations, while lithium is used as an adjunct to radioactive iodine (rai) therapy in graves’ disease with low raiu. in this report, both drugs used in combination, overcame low iodine-131 uptake in a graves’ patient. clinical case: a 39-year old female with graves’ disease...
