Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

328
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

338
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

204
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

266
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radiological Investigation I: X-ray and CT

517
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Area of Science:

  • Neuroradiology
  • Medical Education
  • Radiology Procedures

Background:

  • Fluoroscopy-guided lumbar punctures (FGLPs) are increasingly performed by radiology trainees.
  • The impact of FGLPs on resident productivity in dictating cross-sectional neuroimaging reports is not well-studied.

Purpose of the Study:

  • To evaluate the relationship between the number of FGLPs performed by residents and the number of cross-sectional neuroimaging studies they dictate during their neuroradiology rotation.

Main Methods:

  • Retrospective review of FGLPs, myelograms, and dictated neuroimaging studies (CT and MRI) by radiology residents from July 2008 to December 2017.
  • Poisson regression analysis to examine the relationship between FGLP volume and daily dictated studies.

Main Results:

  • 84 radiology residents performed 3437 FGLPs and myelograms and dictated 33402 cross-sectional studies.
  • A significant exponential decrease in dictated studies was observed with an increasing number of FGLPs performed (P = 0.0001).
  • A formula was derived to predict the adjusted number of studies dictated based on FGLP volume.

Conclusions:

  • Performing FGLPs significantly impacts radiology residents' ability to dictate neuroimaging reports.
  • Recommendations include establishing guidelines for FGLP referrals, encouraging bedside lumbar puncture attempts, and distributing FGLPs equitably among trainees.
