Objectives: To investigate the time course of the development of acquired and experimental lymphedema. Methods: We studied an experimental model of acute post surgical lymphedema in the tails of female hairless mice. The procedures that remove the skin and subcutaneous tissue in tails of the mice (5-10 mm from tail base) were performed, and then the murine has acquired lymphatic insufficiency. ...

Cardiac and respiratory motion can cause artifacts in computed tomography scans of the chest. The authors describe a new method for reducing these artifacts called pixel-specific back-projection (PSBP). PSBP reduces artifacts caused by in-plane motion by reconstructing each pixel in a frame of reference that moves with the in-plane motion in the volume being scanned. The motion of the frame of ...

RESULTS: Four hundred patients were referred with a diagnosis of “lymphedema”; 70% were female and 30% were children. Lymphedema was confirmed in 73% of the cohort: primary (56%) and secondary (44%). Twenty-seven percent of patients labeled with “lymphedema” had another condition. Before referral, only 4% of the cohort underwent lymphoscintigraphy (the gold standard diagnostic test for lymphede...

The diagnosis of back pain in the young athlete should be specific and not attributed to nonspecific, mechanical causes. Risk factor identification and intervention are required. Treatment is then initiated in a specific pattern, addressing flexibility and muscular imbalances. Bracing is often used to allow healing of growth tissue. The lumbosacral orthosis may be molded in a lordotic posture t...

This study proposes an umbrella deployment of swarm intelligence algorithm, such as stochastic diffusion search for medical imaging applications. After summarising the results of some previous works which shows how the algorithm assists in the identification of metastasis in bone scans and microcalcifications on mammographs, for the first time, the use of the algorithm in assessing the CT image...

OBJECTIVE The aim of this study is to evaluate the efficiency of gamma probe guided osteoid osteoma surgery and the applicability of quantitative analyses obtained from preoperative bone scan images. MATERIAL AND METHODS This study involved 12 osteoid osteoma patients who were treated with gamma probe guided surgery after preoperative bone scan. The calculated contrast ratios between nidus an...

Fifteen cases of primary sacral pathology were analyzed. High-resolution computed tomography was found to be the most accurate means of studying these cases. Certain anatomic changes involving the central canal and sacral foramina were found to be helpful in determining the type of pathology. Although conventional plain films, radionuclide bone scans, and myelography were useful in certain case...

Three elderly patients with acetabular fractures not evident on the initial plain radiographs are presented. All had a fall and were unable to bear weight. Cross-sectional imaging and repeated plain radiography confirmed fractures of the acetabulum. Occult acetabular fractures may occur in elderly patients after a fall and present with persistent discomfort and difficulty walking. When there is...
