Acute Kidney Injury IV: Diagnostic Studies and Prevention

271
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Imaging Studies VII: Vascular Imaging

313
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Radiology
  • Nephrology
  • Medical Imaging

Background:

  • Post-contrast acute kidney injury (PC-AKI) is a significant concern in diagnostic imaging using iodinated contrast agents.
  • Understanding healthcare professionals' knowledge is crucial for effective PC-AKI management and prevention.

Purpose of the Study:

  • To assess the knowledge, perceptions, and practices of radiologists and radiographers concerning PC-AKI.
  • To identify specific areas of knowledge gaps and training needs.

Main Methods:

  • A survey was conducted among 80 radiologists and 224 radiographers in South India.
  • A 30-item multiple-choice questionnaire administered via Google Forms was used.

Main Results:

  • A majority correctly identified PC-AKI diagnostic criteria (serum creatinine increase) and key risk factors (diabetes, heart failure, CKD).
  • Some radiographers showed misconceptions regarding diagnostic markers and PC-AKI prevention.
  • Radiologists showed a higher preference for immediate CT in polytrauma, even before renal function results.

Conclusions:

  • While basic knowledge of PC-AKI is prevalent, significant gaps exist, particularly in understanding prevention strategies and managing specific patient populations (emergency, pediatric, pregnant).
  • Targeted training for radiographers is essential to improve PC-AKI awareness and management.
  • Further research into optimal practices for high-risk scenarios is warranted.
