Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

74
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 I: X-ray and CT

182
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

86
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...

Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

70
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

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

Imaging Studies for Cardiovascular System III: X-Ray

114
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...

Lower GI Series: Barium Enema01:23

Lower GI Series: Barium Enema

147
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Area of Science:

  • Radiology
  • Gastroenterology
  • Bariatric Surgery

Background:

  • Rising obesity rates drive increased bariatric surgery prevalence in the US.
  • Bariatric procedures carry risks and complications, often visualized radiologically.
  • Traditional fluoroscopy is complemented by advanced cross-sectional imaging for complication detection.

Purpose of the Study:

  • To review imaging findings and complications of common bariatric surgeries.
  • To provide a resource for radiologists, emergency physicians, and surgeons.
  • To focus on Roux-en-Y gastric bypass, adjustable gastric band, and sleeve gastrectomy.

Main Methods:

  • Comprehensive review of radiological studies.
  • Focus on computed tomography (CT) and CT-angiography (CTA) modalities.
  • Inclusion of fluoroscopy where relevant for anatomical evaluation.

Main Results:

  • Detailed presentation of imaging findings for Roux-en-Y gastric bypass, adjustable gastric band, and sleeve gastrectomy.
  • Characterization of common and major post-operative complications.
  • Exclusion of less common procedures like OAGB and SAIDS due to regional prevalence.

Conclusions:

  • CT and CTA are essential for diagnosing bariatric surgery complications.
  • Familiarity with these imaging findings is crucial for clinicians managing post-operative patients.
  • This review serves as a practical guide to the radiological manifestations of bariatric surgery complications.
