There are various modalities of joint imaging e.g. conventional radiography (CR), computed tomography (CT), magnetic resonance imaging (MRI), bone scintigraphy, positron emission tomography (PET), ultrasonography (US), bone densitography. CR shows only bone lesions, while CT demonstrate both bone and soft-tissue changes. MRI is the best modality at showing soft tissue contrast than CT scan and ...

PURPOSE To evaluate the relative involvement of tibial stress injuries using high-resolution axial MR imaging and the correlation with MR and radiographic images. METHODS A total of 33 patients with exercise-induced tibial pain were evaluated. All patients underwent radiograph and high-resolution axial MR imaging. Radiographs were taken at initial presentation and 4 weeks later. High-resoluti...

Twenty-one patients with medullary thyroid carcinoma were studied prospectively with Tc-99m (V) DMSA after surgery. Pentavalent DMSA scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. Finally, seven patients with surgical or other imaging documentation were selected for this paper. Most of these patients were asymptomatic. Six patients had hypercalcitonemia ...

Engineered Vascularized Flaps In article number 2008687, Shulamit Levenberg and co-workers fabricate composite neo-tissue flaps by combining polymeric matrices decellularized bone. These are perfused in vivo using hosts via a potent neo-vascular network. imaging is utilized to show how support long-term bone repair vascularization. This methodology may one day replace autologous tissue harvest ...

isolated skeletal metastasis to the bony calvarium is extremely rare in patients with squamous cell carcinoma of the uterine cervix. we describe the clinical and imaging findings in a case of squamous cell carcinoma of the uterine cervix with metastases to the bony calvarium as the sole site of metastasis. the patient was a 65-year-old woman with squamous cell carcinoma of the uterine cervix, f...

Bone microstructure has usually been assessed by obtaining samples invasively and analyzing them with conventional histomorphometric methods. Improvements in high-resolution image acquisition systems have enabled non-invasive assessment of bone morphology and a more precise 3-D evaluation by means of "virtual biopsies", permitting bone assessment in regeneration or remodeling processes. Among o...

Bone wax used in neurosurgical procedures is a rare cause of complications after surgery. We present a patient who developed paraplegia following thoracic spine surgery. A subsequent MR imaging study demonstrated a signal void that resembled postoperative air but appeared to cause cord compression and proved after a second surgery to represent bone wax. Recognizing the MR imaging and CT charact...

Diagnostic imaging plays a pivotal role in the initial detection, characterization, pre-operative assessment and long term follow-up of malignant bone tumors. The purpose of this brief review is to discuss the specific role of the different imaging modalities in the diagnostic work-up of malignant bone tumors. The imaging features, with emphasis on standard radiography, allowing differentiation...

Bone is the most common site to which breast cancer metastasizes. Imaging-by skeletal scintigraphy, plain radiography, computed tomography, or magnetic resonance imaging-is an essential part, and positron emission tomography or single-photon emission computed tomography have a potential of evaluating bone metastases, but no consensus exists as to the best modality for diagnosing the lesion and ...

The development of MR imaging has been a great advance in the imaging of bone marrow disorders. MR imaging exhibits excellent soft-tissue contrast and therefore has a greater sensitivity for marrow disease than did previously available modalities. This article reviews the normal morphology and appearance of bone marrow, describes the MR appearance of normal bone marrow, and discusses the MR fin...
