Cortical Thickness and Trabecular Pattern of the Femoral Neck as a Measure of Osteopenia

Publikováno v: Investigative Radiology. 25:116-1119

The pelvic radiographs of 312 patients aged 18 to 92 years were reviewed to determine if the Singh index was valid or not. The cortical thickness of the lower part of the femoral calcar, the stress index (body weight, physical activity, and femoral n

Finger joint swelling: correlation with age, gender, and manual labor

Autor: Peter B. Dean, Pekka Virtama, Pekka Makela

Publikováno v: American Journal of Roentgenology. 132:939-943

A soft tissue immersion radiography technique was used to study changes in 4,648 finger joints of 166 patients free from signs of inflammatory joint disease. An age-specific correlation was found for joint swelling, joint space narrowing, joint margi

Determining growth rates of focal lesions of bone from radiographs

Autor: A J Wilson, F Dittrich, Gwilym S. Lodwick, Corinne Farrell, Pekka Virtama

Publikováno v: Radiology. 134:577-583

Rate of growth divides focal lesions of bone into two classes which are largely mutually exclusive. Not all focal lesions require biopsy, and grading is especially helpful in deciding which should be biopsied and which may be safely followed. The sta

Direct Measurement of the Effect of Film Miniaturization on Diagnostic Accuracy

Autor: Erkki L. Koivisto, James L. Lehr, Corinne Farrell, Pekka Virtama, Melvin O. Braaten, Gwilym S. Lodwick

Publikováno v: Radiology. 118:257-263

A method for directly measuring the reduction in diagnostic accuracy incurred by altering original radiographs was applied to evaluate a 35 mm film system. A total of 4,290 readings of 2,145 proved cases were collected. Analysis of the results indica

Changes of the Digital Arteries in Rheumatoid Arthritis: A Study with the Aid of Post Mortem Brachial Arteriography

Autor: Pekka Virtama

Publikováno v: Scandinavian Journal of Rheumatology. 5:304-313

SummaryTen cases of rheumatoid arthritis and twenty control cases were investigated with the aid of post-mortem brachial arteriography. Fine-grain X-ray film was used so as to render it possible to magnify the images by eight diameters. The alteratio
