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...

Imaging Studies I: CT and MRI

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...

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Imaging Studies for Cardiovascular System V: CT

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...

Summary

New findings on postoperative CT scans are common in traumatic brain injury (TBI) patients after decompressive craniectomy (DC). A low Glasgow Coma Scale (GCS) score is a key predictor of these new findings.

Area of Science:

  • Neurosurgery
  • Neuroradiology
  • Trauma Surgery

Background:

  • New findings on postoperative CT scans occur in patients undergoing surgery for traumatic brain injury (TBI).
  • Decompressive craniectomy (DC) is a critical intervention for managing severe TBI.

Purpose of the Study:

  • To investigate prognostic factors associated with new findings on early postoperative CT scans in patients who underwent DC for TBI.
  • To identify predictors of postoperative CT abnormalities following decompressive craniectomy.

Main Methods:

  • Retrospective registry-based review of 102 patients who underwent DC for TBI.
  • Analysis of patient demographics, surgical indications, and early postoperative CT findings.
  • Univariate and logistic regression analyses to determine significant prognostic factors.

Main Results:

  • New findings on postoperative CT scans were observed in 25.5% of patients.
  • A Glasgow Coma Scale (GCS) score ≤8 was significantly associated with new postoperative CT findings (P = 0.041).
  • Absence of basal cisterns was also associated in univariate analysis (P = 0.012), but not in logistic regression.

Conclusions:

  • A low GCS score (≤8) is the primary independent predictor of new findings on early postoperative CT scans in TBI patients after DC.
  • TBI patients with a low GCS score undergoing DC warrant immediate postoperative CT evaluation to monitor for new findings.
