Positron Emission Tomography01:29

Positron Emission Tomography

7.9K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

570
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 for Cardiovascular System III: X-Ray

564
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...

Area of Science:

  • Breast pathology
  • Oncology
  • Surgical management

Background:

  • B3 lesions represent a heterogeneous group of breast lesions with uncertain malignant potential.
  • Recent advancements, including vacuum-assisted biopsy, impact B3 lesion diagnosis and management.
  • The Marmot Review has influenced current guidelines for breast lesion management.

Purpose of the Study:

  • To summarize the current clinical management of B3 lesions.
  • To discuss proposed future strategies for managing B3 lesions.
  • To address the complexities and controversies surrounding B3 lesion management.

Main Methods:

  • Literature review of recent publications on B3 lesion management.
  • Analysis of upgrade rates from B3 lesions to malignancy.
  • Discussion of diagnostic techniques, including core biopsy and vacuum-assisted biopsy.

Main Results:

  • B3 lesions can be upgraded to malignancy in up to one-third of cases.
  • The majority of upgrades are to ductal carcinoma in situ or low-grade invasive tumors.
  • Epithelial atypia in B3 lesions is significantly associated with higher upgrade rates.

Conclusions:

  • Current B3 lesion management requires careful consideration of diagnostic findings and patient factors.
  • Future management strategies may involve refined diagnostic criteria and tailored treatment approaches.
  • Addressing the heterogeneity of B3 lesions is crucial for optimizing patient outcomes.
