Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

45
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...

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...

Summary
This summary is machine-generated.

Adding contrast enhanced mammography (CEM) and magnetic resonance imaging (MRI) to conventional imaging (CI) can alter breast cancer surgical plans. However, these changes require careful assessment to prevent potential over or under-treatment.

Area of Science:

  • Breast cancer imaging and surgical planning.
  • Radiology and oncologic surgery decision-making.

Background:

  • Contrast enhanced mammography (CEM) and magnetic resonance imaging (MRI) offer higher accuracy than conventional imaging (CI) for breast cancer staging.
  • The impact of integrating CEM and MRI into surgical planning for breast cancer remains understudied.

Purpose of the Study:

  • To investigate how adding CEM or MRI to conventional imaging (CI) influences surgical plans for breast cancer.
  • To assess the appropriateness of surgical plans modified by contrast imaging.

Main Methods:

  • Mock multidisciplinary teams (MDTs) devised surgical plans (BCS, wider BCS, >1BCS, mastectomy) based on CI, CI+CEM, and CI+MRI.
  • Differences in plans were analyzed, and appropriateness was evaluated against final pathology.
  • Surgical outcomes were compared with the mock-MDT plans.

Main Results:

  • Contrast imaging modified surgical plans for 32.8% of cases (20/61).
  • CEM altered plans in 80% (16/20) and MRI in 85% (17/20) of modified cases.
  • The appropriateness of modified plans varied, with CI+CEM plans being suitable in 37.5% and CI+MRI plans in 52.9% of cases.

Conclusions:

  • Adding CEM or MRI to CI can change surgical plans in up to one-third of breast cancer patients.
  • Modified surgical plans require careful validation, as not all changes were appropriate.
  • Altering surgical plans based on contrast imaging without biopsy confirmation risks overtreatment or undertreatment.
