A mandatory differential diagnosis between postoperative granulomas and tumor recurrence is required whenever space-occupying lesions are detected at the surgical site, few months after removal of the intracranial neoplasm, because these two pathologies can often mimic each other clinically, by imaging techniques and even macroscopically. Since history or signs of inflammation may be lackin...

The aim of this study was to assess whether there is an association between changes in the heart rate and blood pressure after dipyridamole stress and abnormal scan findings detected with gated technetium-99m methoxy isobutylisonitrile (99mTc-MIBI) myocardial perfusion imaging (MPI). A total of 200 consecutive patients with known or suspected coronary artery disease underwent MPI using a 2 days...

To The Editor: In the previous article we reported on a patient with a large sternal foramen leading to an area devoid of tracer activity on planar bone scintigraphy and SPET [1]. These defects may present a certain danger when sterna puncture or acupuncture is performed. Because in our experience with radiography and CT imaging of the chest we had only uncommonly found such defects, we decided...

Abstract The development of new cultivars with improved nitrogen use efficiency (NUE) is key for implementing sustainable agriculture practices. Crop wild relatives (CWRs) provide valuable genetic resources breeding programs aimed at achieving this goal. In study, three eggplant (Solanum melongena) accessions together their advanced backcrosses (ABs; BC3 to BC5 generations) were evaluated 22 mo...

A kinetic modelling approach for the quantification of in vivo tracer studies with dynamic positron emission tomography (PET) is presented. The approach is based on a general compartmental description of the tracer’s fate in vivo and determines a parsimonious model consistent with the measured data. The technique involves the determination of a sparse selection of kinetic basis functions from a...

Recent studies have implicated the prorenin receptor (PRR) is associated with pancreatic tumorigenesis. We therefore investigated the role of PRR in pancreatic tumorigenesis and assessed whether PRR can serve as a target for imaging diagnosis at early stages of PDAC. Here we show that aberrant expression of PRR in premalignant PanIN lesions, and human PDAC samples, and PDAC cell lines, particul...

We present three papillary thyroid carcinoma PTC patients with brain metastases who are unusual in many aspects. The first case is a unique 3mm papillary thyroid microcarcinoma (PTMC) patient with metastases to the cerebrum and lung. The solitary cerebral lesion was identified by iodine-131 whole- body scan ((131)I-WBS) and (131)I single photon emission tomography/computed tomography (SPET/CT)....

BACKGROUND The diagnosis of spondylodiscitis can be difficult, because the patients history, subjective symptoms and physical findings are often inconclusive, particularly in the early stages. AIM To perform an overview on the role of nuclear medicine procedures with single photon emission tomography (SPET) and positron emission tomography (PET) tracers in the diagnosis of spondylodiscitis. ...
