Computed Tomography01:10

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 III: Computed Tomography

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

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...

Imaging Studies I: CT and MRI

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...

Imaging Studies VII: Vascular Imaging

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...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

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.

Area of Science:

  • Oncology
  • Radiology
  • Medical Imaging

Background:

  • Sarcomas are a diverse group of over 50 neoplasm subtypes.
  • Accurate imaging is essential for assessing, characterizing, and staging bone and soft tissue sarcomas.
  • Anatomic imaging (radiographs, CT, MRI) is fundamental for biopsy planning and postoperative evaluation.

Purpose of the Study:

  • To review the role of various imaging modalities in the assessment of sarcomas.
  • To highlight the limitations of anatomic imaging in evaluating treatment response.
  • To discuss emerging functional and molecular imaging techniques for improved sarcoma evaluation.

Main Methods:

  • Review of current literature on imaging techniques for sarcomas.
  • Discussion of established anatomic imaging modalities: radiographs, computed tomography (CT), and magnetic resonance imaging (MRI).
  • Exploration of advanced functional imaging techniques: (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET), dynamic contrast-enhanced MRI (DCE-MRI), and diffusion-weighted imaging (DWI).

Main Results:

  • Anatomic imaging is foundational but may lack accuracy in assessing treatment response.
  • (18)F-fluorodeoxyglucose positron emission tomography is utilized for detecting distant metastases.
  • Newer radiopharmaceuticals like (18)F-fluorodeoxythymidine show promise in differentiating benign from malignant neoplasms.
  • Functional imaging techniques like DCE-MRI and DWI are under development for evaluating treatment response.
