Imaging Studies I: CT and MRI01:14

Imaging Studies I: CT and MRI

93
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...

Radiological Investigation I: X-ray and CT

170
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

73
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 II: Positron Emission Tomography and Scintigraphy

39
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.

Radiological Investigation II: MRI and Ventilation Perfusion Scan

85
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...

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

Imaging Studies for Cardiovascular System III: X-Ray

106
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...

Summary

Combining mammography and ultrasound for breast cancer surveillance shows a higher cancer detection rate than either method alone. Tailoring surveillance to breast density is recommended for optimal outcomes.

Area of Science:

  • Oncology
  • Radiology
  • Medical Imaging

Background:

  • Post-surgical breast cancer surveillance is crucial for early detection of recurrence.
  • Various imaging modalities are employed, each with unique detection capabilities.

Purpose of the Study:

  • To compare the effectiveness of different imaging methods for breast cancer surveillance in the first five years post-surgery.
  • To evaluate the impact of mammographic breast density on cancer detection rates.

Main Methods:

  • Retrospective cohort study of 6371 women undergoing breast cancer surgery.
  • Analysis of imaging surveillance data including mammography, ultrasound (US), and magnetic resonance imaging (MRI) over five years.
  • Comparison of cancer detection rates (CDR) across different imaging combinations.

Main Results:

  • Mammography combined with US showed a significantly higher CDR than mammography alone or US alone.
  • The CDR of combined mammography and US was comparable to MRI-based examinations.
  • A significant interaction between mammographic breast density (MBD) and CDR was observed.

Conclusions:

  • Mammography combined with US is an effective surveillance strategy, comparable to MRI.
  • A personalized surveillance approach considering individual breast density is warranted for improved breast cancer detection.
