Imaging Studies I: CT and MRI01:14

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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
Positron Emission Tomography01:29

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

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.

Brain Imaging01:14

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

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...

Area of Science:

  • Orthopedics
  • Infectious Diseases
  • Radiology

Background:

  • Spinal tuberculosis (Pott's spine) is the most common extrapulmonary form of tuberculosis.
  • It accounts for 2% of all TB cases, 15% of extrapulmonary TB, and 50% of skeletal TB.
  • Hematogenous spread leads to symptoms like back pain, paraplegia, and deformities.

Purpose of the Study:

  • To review the diagnostic modalities for spinal tuberculosis (Pott's spine).
  • To highlight the effectiveness of MRI in diagnosing spinal TB.
  • To discuss recent advancements in imaging techniques.

Main Methods:

  • Literature review using Google Scholar and PubMed.
  • Keywords included: TB, extrapulmonary TB, skeletal TB, spinal TB, Pott's spine, Pott's paraplegia, MRI, and CT.
  • Analysis of diagnostic imaging techniques for spinal TB.

Main Results:

  • Plain radiographs are initial but require 30% bone loss to detect lesions.
  • Computed tomography (CT) offers better bony detail than radiographs.
  • Magnetic resonance imaging (MRI) is the most sensitive modality, detecting disc collapse, abscesses, and marrow edema.

Conclusions:

  • MRI is the gold standard for diagnosing spinal TB due to its high sensitivity.
  • Early histopathological diagnosis can be achieved through guided needle aspiration or biopsy.
  • Diffusion-weighted MRI (DW-MRI) shows promise as an adjunct diagnostic tool.
