It has previously been shown that an iterative constrained least-squares (CLSR) technique using a noise-based constraint may be superior to other methods of renogram deconvolution analysis. To test this hypothesis on real data, renography was perform

SummaryThe biochemical values of 76 patients with suspected cholecystitis were subjected to discriminant analysis. The final diagnoses, i. e. acute cholecystitis, chronic cholecystitis and non-biliary disease, were used as the grouping variable. Chol

Twenty-four patients with unexplained somatic complaints were subjected to a thorough somatic examination. Only when the examination proved negative was the patient entered into the study. The patients were clinically appraised according to criteria

Multivariate statistical methods can be used for objective analysis. The emphasis is on analysing renal function parameters together, not one at a time. The aim is to identify curve parameters useful in making predictions in kidneys with and without

Patients with the clinical diagnosis of acute cholecystitis were studied with intravenous cholecystography and cholescintigraphy. The two examinations alternated in a random order. The final diagnosis was ascertained by surgery in most patients. Eith

Seventy patients with established diagnoses of normal, parenchymally insufficient or acutely obstructed kidneys were subjected to gamma camera renography. Deconvolution was then performed using three main techniques subdivided into six variants. Para

Before deconvolution can be used in renography, it is necessary to decide whether the renal function is sufficiently good to allow it. To see if this decision can be circumvented, an iterative constrained least-squares restoration (CLSR) method was i
