STERNUM TOMOGRAPHIC EVALUATION IN PECTUS PATIENTS: ANALYSIS OF SAGITAL PARAMETERS.

Objective: To evaluate the sagittal tomographic reformatting of the sternum using unpublished radiographic parameters (indexes and angles), comparing them between the different types of pectus, and controls.

Methods: 44 patients with pectus deformities and controls underwent chest CT for analysis. The types of pectus were classified into: inferior (IPC), superior (SPC) and lateral (LPC), and broad (BPE) and localized (LPE).

ANALYSIS OF STERNAL CURVATURE PATTERNS IN PATIENTS WITH PECTUS AND CONTROL.

Objective: To analyze reformatted sagittal sternal tomography images and classify sternal body curvature types, and compare different types of populations with one another and with normal individuals.

Methods: In total, 50 controls and 167 pectus patients were selected for chest CT to analyze the median sagittal plane, of whom 89 had mean age, 12 ± 10 years) and 78 (mean age, 14 ± 10 years). Clinical types of were classified as inferior, superior, or lateral and localized or broad The following types of sternal patterns were defined: gradual vertical curve, gradual posterior curve, gradual anterior curve, proximal third curve, middle third curve, distal third curve, anterior rectilinear, vertical rectilinear, and posterior rectilinear.

MRI of subchondral fractures: a review.

Several authors have recently emphasized the role of magnetic resonance imaging (MRI) in the diagnosis of subchondral fractures. There is increasing interest about this type of fractures, mostly because they have been implicated in the genesis of some well-known destructive articular conditions whose cause was previously undetermined, such as distal clavicular osteolysis, rapidly progressive osteoarthritis of the hip, spontaneous osteonecrosis of the knee and adult-type Freiberg's infraction. Subchondral fractures may ultimately lead to bone collapse, secondary osteonecrosis and severe articular damage, and there may be rapid progression of joint destruction over a period of weeks to months.

Imaging diagnosis of early rheumatoid arthritis.

Early diagnosis of rheumatoid arthritis is essential for its proper management. Currently, the initial phase of rheumatoid arthritis is known to provide a window of therapeutic opportunity. Although the diagnosis is primarily clinical, the development and improvement of laboratory and imaging methods have contributed to earlier diagnosis and determination of procedures in early rheumatoid arthritis.
