A cadaveric study was undertaken to determine the best radiographic method of diagnosing dislocation of the proximal tibio-fibular (PTFJ) joint. Three pairs of cadaver knees were used, the right side serving as a control in each case. Plain radiographs, antero-posterior (AP) lateral and 45 degrees oblique films, and axial computed tomography (CT) scans were(More)
The purpose of this study was to construct and evaluate a statistical model for the quantitative analysis of computed tomographic brain images. Data were derived from standard sections in 34 normal studies. A model representing the intracranial pure tissue and partial volume areas, with allowance for beam hardening, was developed. The average percentage(More)
OBJECTIVE Previous studies have suggested that niacin treatment raises glucose levels in patients with diabetes and may increase the risk of developing diabetes. We undertook a meta-analysis of published and unpublished data from randomised trials to confirm whether an association exists between niacin and new-onset diabetes. METHODS We searched Medline,(More)
A new dual image receptor screen-film combination has been developed by Kodak with the objective of improving mediastinal and retro-cardiac detail whilst retaining good contrast and detail in the lung fields. This system was compared with our standard chest system. The study population was 36 patients with sarcoidosis. A postero-anterior (PA) chest film(More)
The objective of the study was to determine whether or not U.S. normal data for female Vertebral Bone Mineral Density is suitable for use in an Irish population. One hundred and fifty-six healthy Caucasian women of permanent Irish domicile had bone densitometry performed using single energy quantitative computed tomography of L2, L3 and L4 vertebrae. We(More)
The contraction stress test (CST) and nonstress test (NST) are used as fetal health assessments. Severe sickle hemoglobinopathies in the parturient have been shown to place the fetus significantly at risk. This study correlates these fetal health assessment tests with outcome data in 58 pregnancies occurring in women with sickle cell disease. There were 30(More)
Comparison is made between a new asymmetric screen-film combination and a conventional screen-film combination for use in chest radiography. Seven anatomical features were assessed by three consultant radiologists in each of 51 film pairs. A preference was indicated if one system better demonstrated a particular feature. Alternatively, no preference was(More)
