Polymeric micelle of the A₃B-type lactosome comprising (poly(sarcosine))₃-b-poly(l-lactic acid) was labeled with 111In. The 111In-labeled A₃B-type lactosome was administered to the model mice bearing meningeal dissemination and bone metastasis at mandible. With single-photon emission computed tomography (SPECT) imaging, the meningeal dissemination was identified successfully by 111In-labeled A₃...

INTRODUCTION Early diagnosis of spinal metastases is of key importance in further therapeutic management. OBJECTIVES The aim of the study was to assess the reliability of single-photon emission computed tomography (SPECT) or SPECT and computed tomography (SPECT/CT) in the diagnosis of solitary hot nodules in the spine identified by scintigraphy. PATIENTS AND METHODS In this retrospective st...

Transient osteoporosis of the hip (TOH), also referred to as bone marrow edema syndrome (BMES) of the femoral head and neck, is an uncommon and therefore underdiagnosed benign skeletal disorder, affecting primarily women, particularly in their last trimester of pregnancy, and middle-aged men. The disease is characterized by self-limiting hip pain and radiographically evident osteopenia, but the...

BACKGROUND The minimally invasive, balloon-assisted reduction and cement-augmented internal fixation of the tibial plateau is an innovative surgical procedure for tibial plateau fractures. The close proximity of balloons and cement to the knee joint poses a potential risk for osteonecrosis; especially in the case of thin bone lamellae. However, there are no studies about the vitality of the cem...

OBJECTIVE Destructive techniques such as histology and biochemical assays are still regarded the gold standard to study the effects of novel therapies or etiologic aspects of osteoarthritis in small animal models. These techniques are time-consuming and require many animals. Multi-pinhole single photon emission computed tomography (MPH-SPECT) is a relatively novel, high resolution imaging techn...

BACKGROUND The detection of occult bone metastases is a key factor in determining the management of patients with renal cell carcinoma (RCC), especially when curative surgery is considered. This prospective study assessed the sensitivity of (18)F-labelled sodium fluoride in conjunction with positron emission tomography/computed tomography ((18)F-NaF PET/CT) for detecting RCC bone metastases, co...

The complex anatomy and function of the foot and ankle can make it difficult to determine the cause of symptoms in patients with foot and ankle pathology. Following initial clinical and radiographic assessment, additional imaging with magnetic resonance imaging may be required, which is often seen as the modality of choice. Although sensitive to pathological changes in bone metabolism and vascu...

BACKGROUND/AIM Bone scintigraphy is well-known method for the detection of neoplastic lesions with a high sensitivity and, at the same time, a lower specificity. On the other hand magnetic resonance imaging (MRI) is previously established noninvasive imaging method regar ding its diagnostic specificity. The aim of this study was to determine the possibilities and to correlate two different diag...

Objective：To evaluate the value of single-photon emission computerized tomography (SPECT) combined with CT and MRI in diagnosis bone metastasis malignant tumors. Method：Eighty patients from tumors who admitted to Affiliated Hospital Chengde Medical College were selected March 2019 June 2021. SPECT imaging, used analyze regional distribution primary tumor efficacy three detection methods metasta...
