■ Describe physiopathologic features and clinical manifestations of MM and associated relevant treatment considerations.■ Discuss updated diagnostic criteria and indications for MM, as well as advantages and limitations of different WB imaging modalities.■ Identify and interpret imaging findings of MM for diagnosis, follow-up, complications assessment, and treatment response evaluation.
ObjectiveTo determine the presence of linear relationship between renal cortical thickness,
bipolar length, and parenchymal thickness in chronic kidney disease patients
presenting with different estimated glomerular filtration rates (GFRs) and to
assess the reproducibility of these measurements using ultrasonography.Materials and MethodsUltrasonography was performed in 54 chronic renal failure patients. The scans were
performed by two independent and blinded radiologists. The estimated GFR was
calculated using the Cockcroft-Gault equation. Interobserver agreement was
calculated and a linear correlation coefficient (r) was determined in order to
establish the relationship between the different renal measurements and estimated
GFR.ResultsThe correlation between GFR and measurements of renal cortical thickness, bipolar
length, and parenchymal thickness was, respectively, moderate (r = 0.478;
p < 0.001), poor (r = 0.380; p = 0.004),
and poor (r = 0.277; p = 0.116). The interobserver agreement was
considered excellent (0.754) for measurements of cortical thickness and bipolar
length (0.833), and satisfactory for parenchymal thickness (0.523).ConclusionThe interobserver reproducibility for renal measurements obtained was good. A
moderate correlation was observed between estimated GFR and cortical thickness,
but bipolar length and parenchymal thickness were poorly correlated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
