“…Information regarding the echogenicity and kidney size is valuable for the guidance of physicians in an appropriate and suitable manner of decision making in the acute kidney injury management. Eliminating the probability of significant decision making is one of the chief efficacies of ultrasound in this setting [6].…”

“…99m Technetium (Tc) refers to renal isotope within imaging of nuclear medicine. It has been found effective because of its good imaging proficiency with little radiation doses and its short half-life of about six hours [6]. The use of 99mTc-MAG3 scan to study RBF may be effective in the setting of acute kidney injury, but it is not broadly used.…”

Article HistoryObjective: The study aims to assess the value of nuclear medicine and ultrasonography for diagnosing renal diseases among patients of different ages. Method: Quantitative analysis has been opted for evaluating the effectiveness of both imaging modalities for the diagnosis of renal diseases. 80 patients were targeted, who were having renal disease indications and they were diagnosed through modalities. The outcomes of both imaging techniques were compared through data analysis. Results: Positive findings of the nuclear medicine were observed between the age groups 0-12 years (58.1%), 13-24 years (16.1%), 25-36 years (1.6%), 37-48 years (9.7%), 61-72 years (3.1%) and 73-84 (8.1%) years of patients. Concerning the ultrasonography technique, positive effects were observed among the patients of age-group 0-12 years (58.7%), 13-24 years (17.5%), 25-36 years (3.2%), 49-60 years (3.2%) and 73-84 years (3.2%). The sensitivity rate for nuclear medicine was 100% as compared to ultrasonography, which was 93.6%. However, the specificity and accuracy rates for nuclear medicine were 78.4%, and 21.5%; however, similar rates for ultrasonography were 79.7%, and 13.92%, which showed better outcomes of ultrasonography. Conclusion: Ultrasonography was observed showing positive results among all age groups as compared to nuclear medicine imaging modalities. Future studies must focus on other imaging techniques to timely diagnose the disease and initiate the treatment before it get worse. Contribution/Originality:The study contributes to assess the efficiency difference between the nuclear medicine and ultrasonography to effectively analyze the case of the renal patients, before it gets severe. The study further documents the value of nuclear medicine in comparison with ultrasonography for the early diagnosis of renal mortal and morbid complications.

“…In humans, CEUS has already been applied to the study of various kidney diseases, including chronic kidney disease (CKD) [36] (notably DKD [1,37] ), AKI [38] , and kidney transplantation [39] . All of these investigations indicate that CEUS is well-tolerated, and that the subjects experience no side effects due to the contrast agents.…”

This article reviews the application of contrast-enhanced ultrasound (CEUS) in gauging renal microvascular perfusion in diverse renal diseases. The unique nature of the contrast agents used in CEUS provides real-time and quantitative imaging of the vasculature. In addition to the traditional use of CEUS for evaluation of kidney masses, it also emerges as a safe and effective imaging approach to assess microvascular perfusion in diffuse renal lesions, noninvasively. Although the precise CEUS parameters that may best predict disease still warrant systematic evaluation, animal models and limited clinical trials in humans raise hopes that CEUS could outcompete competing modalities as a first-line tool for assessing renal perfusion non-invasively, even in ailments such as acute kidney injury and chronic kidney disease.

“…Clinical manifestations of post-renal obstructive uropathy vary with the site, degree and rapidity of obstruction [Kapoor, Chan 2001]. B-mode ultrasonography is a very useful imaging tool to rule out the possibly of urinary tract obstruction as a cause of AKI [Kalantarinia 2009]. Early detection of urinary tract obstruction may prevent patients from progressing to established AKI by early release of urinary obstruction [Choudhury 2010].…”
