Computed Tomography01:10

Computed Tomography

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 II: MRI and Ventilation Perfusion Scan

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 III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Summary
This summary is machine-generated.

A new spiral computed tomographic (CT) subtraction imaging technique accurately predicts postoperative lung function in lung cancer patients with chronic obstructive pulmonary disease, matching radioisotope perfusion scintigraphy. This may reduce the need for nuclear imaging.

Area of Science:

  • Pulmonary Medicine
  • Radiology
  • Thoracic Surgery

Background:

  • Lung resection for bronchogenic carcinoma in patients with COPD requires precise lung function assessment.
  • Perioperative complications and long-term disability are risks associated with inadequate preoperative evaluation.

Purpose of the Study:

  • To evaluate a novel spiral CT subtraction imaging technique for predicting postoperative lung function.
  • To compare the accuracy of CT subtraction imaging with radioisotope perfusion scintigraphy.

Main Methods:

  • 25 patients with resectable lung cancer and COPD underwent lung function tests, radioisotope perfusion scintigraphy, and spiral CT subtraction imaging.
  • Postoperative lung function was assessed and compared to predicted values from both imaging modalities.

Main Results:

  • Spiral CT subtraction imaging showed high agreement with radioisotope perfusion scintigraphy in predicting postoperative forced expiratory volume in 1 second (FEV1) (r=0.96).
  • Both methods strongly correlated with actual postoperative FEV1 (CT: r=0.87; scintigraphy: r=0.88).

Conclusions:

  • CT subtraction imaging is as accurate as radioisotope perfusion scintigraphy for predicting postoperative lung function.
  • This CT technique may eliminate the need for nuclear imaging in preoperative assessments for high-risk lung cancer patients.
