FDG PET brain scans were obtained and visually graded by an experienced nuclear medicine physician as to the presence of classic bilateral temporo-parietal hypometabolism as seen in Alzheimer's type dementia.
The amount of radioactivity taken up by each segment was visually graded and assigned an uptake score of 0 (normal), 1 (mildly reduced), 2 (moderately reduced), 3 (severely reduced), or 4 (none).
All the timber were visually graded, dynamically (vibration and acoustic methods were used) and statically (four point bending test) tested, to calculate the actual MOE/MOR.
The green veneer sheets were visually graded to four classes (face, core, composer, waste) according to their splitting severity by the technical manager in NPI.
FDG uptake in the abnormality was also visually graded in comparison to mediastinal activity.
The intrinsic tooth shade was visually graded using a traditional Vita® Lumin Shade guide as a reference standard (VITA Zahnfabrik, H.Rauter GmbH & Co. KG, D-79713 Bad Säckingen, Germany).
The intensity of positive staining was visually graded on a scale of 1 3.
The following data were obtained from records: date and number of previous ESIs, age, sex, BMI range, presence of diabetes, HA1C, mean glucose, random glucose, triglycerides, cholesterol, LDL, HDL, CPK, SGPT, SGOT, ALK- PHOS, uric acid and creatinine.The severity of EL was graded by visually assessing the degree of compression and distortion of the thecal sac on all T1 images.
Both readers visually inspected the strip and graded the intensity of any visualized test band by comparing test band color intensity to the color intensity of the series of bands on a manufacturer-supplied paper reference card.
The EOD was graded into five categories by visually counting the total number of bone lesions on the bone scan (Soloway et al, 1988).
