Imaging Studies I: Kidney, Ureter, and Bladder Studies01:28

Imaging Studies I: Kidney, Ureter, and Bladder Studies

489
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...

Imaging Studies III: Computed Tomography

492
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

538
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Ultrasonography01:17

Ultrasonography

8.2K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

678
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

518
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Summary

Systemic amyloidosis can affect abdominal organs, often with non-specific signs. Imaging findings like liver heterogeneity and spleen signal intensity on MRI can aid diagnosis in suspected cases.

Area of Science:

  • Radiology
  • Gastroenterology
  • Internal Medicine

Background:

  • Systemic amyloidosis involves organ infiltration, frequently affecting the abdomen.
  • Abdominal manifestations of amyloidosis often present insidiously with nonspecific findings.
  • Accurate diagnosis relies on recognizing characteristic imaging features.

Purpose of the Study:

  • To illustrate computed tomography (CT) and magnetic resonance imaging (MRI) findings of abdominal amyloidosis.
  • To highlight key imaging features that suggest abdominal organ involvement in systemic amyloidosis.
  • To correlate imaging findings with clinical suspicion and patient history.

Main Methods:

  • Pictorial essay utilizing CT and MRI scans.
  • Review of imaging findings in patients with confirmed systemic amyloidosis.
  • Focus on characteristic organ-specific changes.

Main Results:

  • Heterogeneous liver appearance on imaging.
  • Periportal space involvement in the liver.
  • Diffuse low T2 signal intensity of the spleen on MRI.
  • Bowel wall thickening may be observed.

Conclusions:

  • Specific imaging findings can suggest abdominal amyloidosis.
  • Liver heterogeneity, splenic signal changes, and bowel thickening are important indicators.
  • Integration of imaging findings with clinical context (inflammatory disease, suspicion) is crucial for diagnosis.
