Efficacy of three projective techniques in differentiating brain damage among subjects with normal IQs.

Obtained substantial differentiation between brain-damaged (N = 25) and non-brain-damaged (N = 25) groups of average intelligence with the WAIS, Rorschach and Hand Test. The use of projective tests in diagnosing neurological impairment was encouraged, but it was cautioned that brain damage and IQ are heavily interrleated, sometimes in complex ways, and that reliable signs of organicity may vary with the Ss level of intelligence.

MR cholangiopancreatography: prospective comparison of a breath-hold 2D projection technique with diagnostic ERCP.

The aim of this study was to compare prospectively a breath-hold projection magnetic resonance cholangiopancreatography (MRCP) technique with diagnostic endoscopic retrograde cholangiopancreatography (ERCP). Seventy-six patients with suspected strictures or choledocholithiasis were referred for MRCP and subsequent ERCP examination, which were performed within 4 h of each other. The MRCP technique was performed using fat-suppressed rapid acquisition with relaxation enhancement (RARE) projection images obtained in standardised planes with additional targeted projections as required by the supervising radiologist. Two radiologists (in consensus) assessed the MRCP results prospectively and independently for the presence of bile duct calculi, strictures, non-specific biliary dilatation and pancreatic duct dilatation, and recorded a single primary diagnosis. The ERCP was assessed prospectively and independently by a single endoscopist and used as a gold standard for comparison with MRCP. Diagnostic agreement was assessed by the Kappa statistic. The MRCP technique failed in two patients and ERCP in five. In the remaining 69 referrals ERCP demonstrated normal findings in 23 cases, strictures in 19 cases, choledocholithiasis in 9 cases, non-specific biliary dilatation in 14 cases and chronic pancreatitis in 4 cases. The MRCP technique correctly demonstrated 22 of 23 normal cases, 19 strictures with one false positive (sensitivity 100 %, specificity 98 %), all 9 cases of choledocholithiasis with two false positives (sensitivity 100 %, specificity 97 %), 12 of 14 cases of non-specific biliary dilatation and only 1 of 4 cases of chronic pancreatitis. There was overall good agreement for diagnosis based on a kappa value of 0.88. Breath-hold projection MRCP can provide non-invasively comparable diagnostic information to diagnostic ERCP for suspected choledocholithiasis and biliary strictures and may allow more selective use of therapeutic ERCP.

Maximizing split-half reliability estimates for projective techniques.

Hand Test data from comparable sets of clinical samples were analyzed for reliability using the usual odd-even split and then also calculating all possible (126) split-half combinations. Maximum stable reliabilities were obtained which were substantially superior to the odd-even method. It was concluded that projective tests are probably more internally reliable than has heretofore been reported.
