Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

535
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...

Computed Tomography01:10

Computed Tomography

9.1K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation I: X-ray and CT

1.4K
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 II: MRI and Ventilation Perfusion Scan

742
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...

Area of Science:

  • Radiology
  • Pathology
  • Oncology

Background:

  • Composite and collision tumors are distinct neoplasms coexisting within a single organ.
  • Radiological literature often uses these terms interchangeably, causing diagnostic confusion.
  • Understanding their unique histological and etiological differences is crucial.

Purpose of the Study:

  • To review abdominal composite and collision tumors.
  • To highlight key radiographic and pathological features.
  • To improve recognition, diagnosis, and management.

Main Methods:

  • Literature review of abdominal composite and collision tumors.
  • Discussion of rare hepatic, renal, and adrenal case studies.
  • Analysis of hallmark radiographic and pathological presentations.

Main Results:

  • Composite tumors exhibit histological intermingling, often from a common driver mutation.
  • Collision tumors lack intermingling and may arise from coincidental neoplastic changes.
  • Distinct presentations in hepatic, renal, and adrenal cases are discussed.

Conclusions:

  • Accurate differentiation between composite and collision tumors is essential.
  • Understanding unique presentations aids in diagnosis and management.
  • This review provides a foundation for recognizing these rare entities.
