Imaging Studies III: Computed Tomography

35
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...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

33
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...

Ultrasonography01:17

Ultrasonography

4.7K
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...

Assessment of the Abdomen III: Palpation01:23

Assessment of the Abdomen III: Palpation

999
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Area of Science:

  • Pediatric Radiology
  • Diagnostic Imaging
  • Oncology

Background:

  • Palpable tumors in children present a unique diagnostic challenge compared to adults.
  • The differential diagnosis for pediatric masses is extensive and often involves rare etiologies.
  • Most childhood palpable lesions are benign, with malignancy estimated at only 1%.

Purpose of the Study:

  • To review the clinical and radiological characteristics of common pediatric palpable lesions.
  • To highlight key features for accurate diagnosis of childhood tumors.
  • To guide radiologists in differentiating benign from malignant pediatric masses.

Main Methods:

  • Review of clinical presentations of pediatric palpable tumors.
  • Analysis of ultrasonography findings for common pediatric lesions.
  • Correlation of imaging characteristics with histopathological diagnoses.

Main Results:

  • Ultrasonography is the primary, cost-effective, and safe imaging modality for pediatric palpable masses.
  • Characteristic imaging features aid in distinguishing common benign pediatric tumors.
  • Accurate diagnosis prevents unnecessary invasive procedures and treatment delays.

Conclusions:

  • Understanding common pediatric palpable lesions improves diagnostic accuracy.
  • Ultrasonography plays a crucial role in the initial evaluation of childhood tumors.
  • Timely and correct diagnosis ensures appropriate management for pediatric patients.
