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 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...

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...

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...
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 II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Summary
This summary is machine-generated.

New postoperative brain lesions on CT scans are predicted by severe head injury (Glasgow Coma Scale ≤ 8), absence of basal cistern, and decompressive craniectomy. Early postoperative CT is recommended for high-risk patients.

Area of Science:

  • Neurosurgery
  • Radiology
  • Trauma Surgery

Background:

  • Intracranial lesions may expand post-surgery, with known risk factors.
  • New lesions, undetected preoperatively, can appear on postoperative CT scans.
  • Factors predicting these new postoperative lesions are not well understood.

Purpose of the Study:

  • To investigate predictive factors for new findings (NFs) on early postoperative computed tomography (CT) after traumatic brain injury surgery.

Main Methods:

  • Retrospective registry-based review of 186 patients with traumatic brain injury.
  • Analysis of prognostic factors for NFs on early postoperative CT scans.

Main Results:

  • 15.6% of patients showed new findings on postoperative CT.
  • Significant predictors included low Glasgow Coma Scale (GCS) score (≤8), absence of basal cistern, and decompressive craniectomy.
  • Logistic regression identified decompressive craniectomy (OR 8.1), GCS ≤ 8 (OR 3.4), and absent basal cistern (OR 3.5) as significant factors.

Conclusions:

  • Early postoperative CT is advisable for head trauma patients with identified predictive factors for new lesions.
  • Identifying patients at risk for new postoperative findings can guide imaging decisions.
