Edge enhancement of ECG-gated cardiac images using directional masks

ECG-gated images were processed by a computer using a nonlinear digital filter and directional masks to improve delineation of cardiac chamber boundaries and identification of the aortic and mitral valve planes. This technique proved to be satisfactory in 30 patients with documented coronary or valvular heart disease.     

Preliminary data on dermis and subcutis thickness in adults with type 1 and 2 diabetes mellitus

We compared the thickness of both dermis and subcutis (measured using ultrasound) in overweight and obese adults with type 1 (n = 10) or type 2 (n = 8) diabetes mellitus. When adjusted for confounding factors, patients with type 1 diabetes had thicker subcutis than those with type 2 diabetes, with this difference being particularly marked in the abdomen. There were no observed differences in dermal thickness between the groups.
