X-Ray Reconstruction of Moving Morphology (XROMM) comprises a set of 3D X-ray motion analysis techniques that merge motion data from in vivo X-ray videos with skeletal morphology data from bone scans into precise and accurate animations of 3D bones moving in 3D space. XROMM methods include: (1) manual alignment (registration) of bone models to video sequences, i.e., Scientific Rotoscoping; (2) ...

The digital era has witnessed an exponential growth in bone imaging as new modalities and analytic techniques improve the potential for noninvasive study of bone anatomy, physiology, and pathophysiology. Bone imaging very much lends itself to input across medical and engineering disciplines. It is in part a reflection of this multidisciplinary input that developments in the field of bone imagin...

Although there are many reports of osteoid os teoma in the literature, we were able to find only one case in which a bone scan was performed (1). The scan showed no definite lesion. McAfee has ad vised us that he has performed imaging studies on two proven instances of osteoid osteoma, both dem onstrating markedly increased uptake, but he is Un able to cite a specific reference in the literatur...

Objective The aim of the present study is to report on the reduction of edema of lymphedematous arms just by treating the lower limbs. Methods A 16-year-old girl reported that she has started having right lower limb edema at the age of three. At age 13, she performed a lymphoscintigraphy that confirmed the diagnosis of primary lymphedema of the four limbs. Recently she sought treatment at the...

Inguinal hernia is a well-known entity that usually affects males. The most common herniated organs are parts of the bowel, omentum, or fat. Urinary bladder herniation into the inguinal region is very rare and is often diagnosed during inguinal hernia surgery. This case highlights the importance of additional views and anatomic imaging to accurately interpret the unusual scan findings.

The assumptions of conventional whole-rock and mineral isochron radioisotope dating were tested using a suite of radioisotopes from two Precambrian rocks. Amphibolite from the Beartooth Mountains of Wyoming shows evidence of thorough metamorphism by isochemical processes from andesite by an early Precambrian magma-intrusion event. A diabase sill, exposed within the wall of Grand Canyon at Bass ...

Case 1 A 70-year-old man presenting with an initial episode of urinary retention was subsequently diagnosed to have prostate adenocarcinoma (Gleason’s grade 4+4) upon transrectal ultrasound guided biopsy of the prostate. His initial prostate-specific antigen (PSA) level was 30 ug/mL. Staging computed tomography (CT) scan revealed a locally advanced prostatic tumour with bilateral hydronephrosis...

Primary sternal osteomyelitis is a rare condition. Only few cases have been reported in the English literature. We describe the case of a young woman presenting with persistent fever and chest pain. Radionuclide bone scan and computed tomography of the chest were consistent with metastatic neoplasm. Surgical intervention, however, revealed primary staphylococcal osteomyelitis and the patient wa...

Radionuclide bone scanning has been a mainstay in the noninvasive evaluation of bone disease for decades. While SPECT imaging provides better evaluation of abnormal tracer uptake than planar scintigraphy, it still produces less than ideal anatomic localization. The introduction of hybrid SPECT/CT devices such as BrightView XCT has added value in improved localization of skeletal lesions and imp...

Intra- or periarticular osteoid osteoma (00) is uncommon, and therefore a diagnostic challenge. Symptoms are: chronic synovitis, decreased range of motion, joint effusion, and joint contracture. Radiographically, the classical perifocal sclerotic margin is often absent, which leads to a significant delay in diagnosis. The authors retrospectively studied 50 cases of intra- and peri-articular OO,...
