BACKGROUND: Spinal cord stimulation (SCS) reduces sympathetic activity in animal models of heart failure with reduced ejection fraction (HF) but limited data exist of SCS in patients with HF. The aim of the present study was to test the primary hypothesis that SCS reduces cardiac sympathetic nerve activity in HF patients. Secondary hypotheses were that SCS improves left ventricular function and dimension, exercise capacity and clinical variables relevant to HF. METHODS: HF patients with a SCS device previously participating in the DEFEAT-HF trial were included in this crossover study with 6-week intervention periods (SCS-ON and SCS-OFF)...

Imaging modalities including radiography, computed tomography (CT), and magnetic resonance imaging (MRI) are necessary for the diagnosis of bone and soft tissue tumors. The history of imaging began with the discovery of X-rays in the 19th century. The development of CT, MRI, ultrasonography, and positron emission tomography (PET) have improved the management of bone and soft tissue tumors. X-ray imaging and CT scans enable the evaluation of bone destruction, periosteal reaction, sclerotic changes in lesions, condition of cortical bone, and ossification...

BACKGROUND: Osteoid osteoma is a primary, benign bone tumour. The characteristic clinical symptom is nocturnal pain at the tumour site that decreases or resolves completely with salicylates and non-steroidal antiinflammatory drugs (NSAIDs). The typical radiological features include a radiolucent area with an osteosclerotic rim. An unusual location or absence of visible abnormalities on conventional radiographs may pose a diagnostic challenge. MATERIAL AND METHODS: We report our clinical experience with osteoid osteoma in 15 patients, with special regard to diagnostic and therapeutic difficulties in two cases...

The post-transplant distal limb syndrome is a not well known entity, with a prevalence of 5% in patients with renal transplant. Its diagnosis is based on clinical symptoms, bone scintigraphy and MRI, it has a benign course and the patient recovers without sequel. We present the case of a 37-year-old male, with medical history of hypertension, Berger's disease in 1999 that required dialysis three times a week for four years (2009-2013) and renal transplant in 2013. The patient consults on January 2014 referring severe pain in both feet, with sudden onset; he remembers the exact date of the beginning of the pain and denies trauma, pain prevents ambulation...

A 7-year-old boy with chief complaint of chronic pelvic pain was referred to our nuclear medicine department for bone scintigraphy. The images showed a focus of radiotracer activity in the right side of pelvic cavity, which is further confirmed as urinary bladder by single-photon emission computed tomography (SPECT) and delayed images. Because of high possibility of mass effect in pelvic cavity, pelvic magnetic resonance imaging (MRI) was performed, and it revealed an unusual dilatation of rectosigmoid colon with no evidence of pelvic mass...

BACKGROUND: Bone SPECT can be used after a femur neck fracture to assess the circulation of the femoral head in the immediate postoperative period because the blood supply is one of the major factors affecting bone uptake of radiotracer on bone scintigraphy. The purpose of our present study was to investigate whether osteonecrosis of the femoral head (OFH) after internal fixation of femoral neck fracture could be predicted by early and late bone SPECT. METHODS: This retrospective cohort study enrolled 44 patients (33 women; mean age, 66...

BACKGROUND: The aim of this study is to assess whether ultra-fast acquisition SPECT/CT (UF-SPECT/CT) can replace standard SPECT/CT (std-SPECT/CT) as "add-on" to whole-body bone scintigraphy (WB-BS) for the investigation of bone metastases. Consecutive cancer patients referred for WB-BS who underwent SPECT/CT in addition to WB-BS were included. Std-SPECT, UF-SPECT, and low-dose CT were performed (std-SPECT: matrix 128 × 128, zoom factor 1, 20 s/view, 32 views; UF-SPECT: identical parameters except for 10 s/view and 16 views, reducing the acquisition time from 11 to 3 min)...

The Erdheim-Chester disease is a rare form of non Langherans histiocytosis. It can be expressed by a multi systemic disease interesting: bone, lung, heart, brain, retro peritoneum, skin and retro-orbital tissue. The diagnosis is established under the radiological aspect, bone scan uptake and immunohistological profile. The bone lesions are almost constant and rather characteristic of bone scintigraphy. We related the case of a young female patient of 26 years old with Erdheim-Chester bone disease. Diagnosis was revealed by diabetes insipidus (nerve damage) and diffuses bones pain...

Despite increasing reliance on CT, MRI, and FDG PET/CT for oncological imaging, whole-body skeletal scintigraphy remains a frontline modality for staging and surveillance of osseous metastatic disease. We present a 54-year-old woman with metastatic breast cancer who received palliative external-beam radiation to the left ilium. Serial follow-up Tc-MDP bone scans demonstrated progressive soft-tissue uptake in her left lower extremity, extending from thigh to leg, with associated enlargement and skin thickening, consistent with lymphedema related to radiation-induced fibrosis...

Metastatic spread of malignant phaeochromocytoma is known to involve multiple organs including the axial skeleton. Its presentation as a solitary lesion in the long bones of the extremities is extremely rare. We report a unique case of solitary metastatic phaeochromocytoma presenting in the distal femur, 16 years after excision of primary abdominal tumor. A 60 year old female, operated for adrenal phaeochromocytoma 16 years back was detected to have a bone tumor in her left distal femur. Chest and abdominal CT evaluation including bone scintigraphy confirmed the lesion to be solitary...

Scaphoid fractures constitute 71% of all carpal bone fractures.(1) Early diagnosis and treatment has significant bearing on fracture union rates and better clinical outcomes. While displaced fractures can be readily seen on plain radiograph, undisplaced fractures can require advanced imaging modalities to confirm that diagnosis. Advanced imaging such as Magnetic Resonance Imaging (MRI), Computerised tomography (CT) and bone scintigraphy are routinely used for the diagnosis of scaphoid fractures but require significant radiation exposure, increased cost and can be difficult to access...
