INTRODUCTION: Global and regional sympathetic activity in the heart can be evaluated using [123 I]meta-iodobenzylguanidine ([123 I]mIBG) imaging. However, [123 I]mIBG is associated with low image spatial resolution and sensitivity in cardiac imaging. We investigated the capability of an F-18-labeled mIBG derivative, meta-(3-[18 F]fluoropropyl)benzylguanidine ([18 F]mFPBG), for identifying ischemic and viable myocardium in a rat model of myocardial infarction. MATERIALS AND METHODS: The ex vivo biodistribution and in vivo metabolic stability of [18 F]mFPBG were investigated in Sprague-Dawley rats...

Background: Unilateral condylar hyperplasia (UCH) of the mandible, or Hypercondylia, is a pathological condition that determines an abnormal growth of the affected condyle.Bone SPECT with Tc99m-diphosphonates is a successful tool in the diagnosis of UCH. EANM guidelines also suggest the use of 18F-NaF PET/CT, though it leads to a higher radiation exposure. Aim: As UCH patients are young, we aimed to develop a low dose 18F-Fluoride PET/CT protocol and compare it to a standard injected activity scan, to assess if the image quality remains unchanged...

Background: The diagnostic performance of SPECT-only imaging for takotsubo cardiomyopathy (TC) is limited due to the lack of coronary artery distribution information. The aim of this study was to evaluate the diagnostic performance of hybrid cardiac SPECT/CT for patients with TC or acute coronary syndrome (ACS). Methods: Twenty-two patients with apical ballooning left ventricular (LV) dysfunction who underwent cardiac perfusion SPECT using 99m Tc-methoxy-isobutyl-isonitrile (MIBI), cardiac fatty-acid metabolism SPECT using 123 I-beta-methyl-P-iodophenyl-pentadecanoic acid (BMIPP), cardiac CT, and hybrid cardiac SPECT/CT imaging were analyzed...

Purpose: To prospectively evaluate the clinical utility of xSPECT/CT Bone, a new reconstruction algorithm for single photon emission tomography (SPECT), and compare it with standard SPECT/CT reconstruction. Methods: Sequential reporting of SPECT/CT followed by xSPECT/CT images in 200 sequential cases commencing August 2015. Differences between the initial SPECT/CT and the final report (after xSPECT/CT reconstruction) were documented and analysed. 12-18 months after the initial study follow-up, clinical data was sought from a subset of cases in which xSPECT/CT changed the primary diagnosis and imaging correlation undertaken in all patients who subsequently had MRI or CT scans of the same region...

A vast spectrum of lower limb bone and joint disorders (hip, knee, ankle, foot) present with a common clinical presentation: limping. Too often this symptom generates an inefficient cascade of imaging studies. This review attempts to optimise the diagnostic effectiveness of bone scintigraphy using the hybrid SPECT/CT technique in relation to the diagnostic clues provided by other imaging modalities, discusses the appropriate clinical indications, optimal scintigraphic procedures and illustrates updated image pattern-oriented reporting...

BACKGROUND: Magnetic resonance imaging (MRI) acquisition/processing techniques assess brain volumes to explore neurodegeneration in Alzheimer's disease (AD). OBJECTIVE: We examined the clinical utility of MSmetrix and investigated if automated MRI volumes could discriminate between groups covering the AD continuum and could be used as a predictor for clinical progression. METHODS: The Belgian Dementia Council initiated a retrospective, multi-center study and analyzed whole brain (WB), grey matter (GM), white matter (WM), cerebrospinal fluid (CSF), cortical GM (CGM) volumes, and WM hyperintensities (WMH) using MSmetrix in the AD continuum...

Dear Editor, Tuberous sclerosis (TS) is an autosomal dominant multisystem disease, which occurs due to genetically determined hyperplasia of ectodermal and mesodermal cells. Clinical manifestations present on the skin and in the nervous system, kidneys, heart, and other organs. Recent studies estimate the incidence of TS at 1/6000 to 1/10,000 live births, and a prevalence in the general population of approximately 1 in 20,000 (1). There are two different genetic loci responsible for TS: 9q34 (TSC1-hamartin) and 16p13...

Worldwide melanoma incidence and mortality are increasing (1). Despite the ongoing research, advanced melanoma is still incurable; therefore, the most appropriate solution seems to be early detection combined with complete surgical excision (2). Since the diagnostic protocol of suspicious lesions includes a complete excision with safety margins (2), the problem of unnecessary scarring is significant. The real challenge in this case is to have a properly formulated diagnosis before acquiring a biopsy. Currently available non-invasive techniques are coherence tomography, digital dermoscopy, and reflectance confocal microscopy...

Axial sesamoiditis or osteitis of the proximal sesamoid bones (PSBs) in the horse is described as a rare condition. The cause remains unknown and speculative, with vascular, infectious, and traumatic aetiologies implicated. It is specifically associated with injury of the palmar or plantar ligament (PL), also known as the intersesamoidean ligament. Imaging findings are generally rewarding and radiological changes are typical, if not pathognomonic, for the condition. Lesions consist of bone lysis at the apical to mid-body axial margins of the PSBs, with variable degrees of joint effusion...

The purpose of this article is to summarize the work and pioneering achievements in the field of orthopedic surgery of the German orthopedic surgeon Karl Ludloff. Ludloff had an impact in the diagnostics, physical examination, orthopedic imaging, and orthopedic surgical technique of his era. He was a pioneer in the surgical treatment of dysplastic hip, anterior cruciate ligament reconstruction, and hallux valgus. His surgical technique for the correction of hallux valgus, initially stabilized with plaster of Paris, remained unpopular among other orthopedic surgeons for decades...

Current guidelines recommend ultrasound (US) for hepatocellular carcinoma (HCC) surveillance in cirrhosis. We assess predictors of decreased US sensitivity for detecting HCC. At a single U.S. center, all HCC patients evaluated for liver transplant (LT) receive an abdominal US. In consecutive patients presenting 2007-2015, untreated lesions found on CT/MRI within 3 months of US were compared with US findings. Multivariable logistic regression models compared US sensitivities by patient characteristics. Of 1008 patients completing LT evaluation, 47...

REVIEW
D L Clarke
Feline obstructive ureteral disease will likely remain a common and frustrating cause of critical illness in cats for the foreseeable future. Since many cats are uraemic and cardiovascularly unstable secondary to obstructive nephropathy, prompt recognition using clinical intuition, blood work and diagnostic imaging is essential to make a timely diagnosis and decision about timing for intervention, if indicated. Multiple surgical and interventional procedures exist for the management of feline ureteral obstructions but there is no ideal technique and all currently available procedures carry risk of infection, re-obstruction, urine leakage and the need for additional procedures in the future...

Purpose: To report a unique case of orbital inflammatory disease which was ultimately diagnosed as granulomatosis with polyangitis (GPA) and thus successfully treated. Observation: A 47 year-old man presented with a rapidly progressive necrotic soft tissue mass within the medial antero-superior aspect of the right eyelid and orbit. He also had transient retinal vasculitis in the left. Serology, histology and imaging were atypical of, but consistent with, GPA. He was thus successfully treated with intravenous rituximab followed by reconstruction of the medial eyelid...
