This study has aimed to evaluate the impact of F18 Fluorodeoxyglucose Positron Emission Tomography-Computed Tomography (FDG PET-CT) in the differential diagnosis of malignant and benign pleural lesions in patients with suspected malignant pleural mesothelioma (MPM).Fifty patients (32 females, 18 males; age range 24–79 years) with pleural thickening, fluid, plaques or calcification on previous...
The sentinel lymph node (SLN) biopsy is currently the procedure of choice for axillary node staging in initial stages of breast cancer. The purpose of this study is to establish our false negative rate within a 5-year follow-up period in 258 patients with breast cancer staged with this procedure.A retrospective study on 258 consecutive T1–T2<3cm pN0 staged breast carcinomas treated from January...
18 F-FDG-PET/CT is widely employed to evaluate lymphoma patients. False positive results are quite frequent, generally due to active phase of inflammation. We describe an unusual PET/CT presentation of a sarcoid-like reaction (SLR) in a patient monitored for Hodgkin Lymphoma characterized by an intense uptake in lymph nodes and multiple bone foci in a PET/CT study. The final diagnosis was obtained...
The most common cause of metastatic involvement of axillary lymph nodes in women is ipsilateral breast cancer. The definition of occult breast malignancy has changed over time. Nowadays, it is considered to exist when it coincides with an isolated metastatic axillary abnormal lymph node in the absence of a palpable tumor in the ipsilateral breast, non-diagnostic breast tumor mammography and no detection...
To know the perceived quality and the levels of patient satisfaction with the Nuclear Medicine (NM) Service.A cross-sectional descriptive study was performed. The authors designed a self-applied questionnaire based on a questionnaire from a survey created by the National Health Service (NHS) of the UK. The answers of 32 items were analyzed, these including 4 social-demographic questions and one open...
Moyamoya disease (MMD) is a cerebrovascular disorder involving stenosis of brain vessels. Brain perfusion SPECT in MMD demonstrates impaired perfusion in ischemic areas. We present a 6-year-old boy with MMD. The patient had numbness on the right arm and simultaneous electroencephalography changes while studying arms up on the table. To differentiate seizure and ischemic symptoms, brain perfusion SPECT...
To analyze the costs of fever of unknown origin (FUO) prior to the PET–CT study. To determine the effectiveness of PET–CT in the diagnosis of FUO. A proposal of diagnostic algorithm.A retrospective study was performed that included 20 patients who had been studied between January 2007 and January 2011, with a mean age of 57.75 years and FUO diagnosis. All underwent a PET–CT study with 18 F-FDG...
Ischemia modified albumin (IMA) is a new marker of ischemia which is used in especially emergency room. Aim of this study is showing the association of IMA with stress induced ischemia on Tc-99m 2-methoxyisobutyl-nitrate (MIBI) myocardial perfusion scintigraphy (MPS).56 patients (23 F, 33 M; 56.04±8.45 years old) were included in our study. Stress-rest two days protocol Tc-99m MIBI MPS single photon...
Patient preparation for FDG PET studies is perhaps more critical and more complex than for any other commonly performed imaging procedure. We report a patient with normal blood glucose level prior to the execution of a PET study in which FDG uptake was virtually zero in internal organs and was very extense in large muscle groups. The patient recognizes ingestion several minutes before the test. Ten...
