Imaging Studies III: Computed Tomography

368
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...

Computed Tomography

8.3K
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...

The Evidence for Evolution

48.2K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Criteria for Causality: Bradford Hill Criteria - II01:28

Criteria for Causality: Bradford Hill Criteria - II

1.2K
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

Criteria for Causality: Bradford Hill Criteria - I

1.1K
The Bradford Hill criteria are a group of principles that provide a framework to determine a causal relationship between a specific factor and a disease. There are nine criteria that are pivotal in assessing causality in epidemiological studies. Here's a closer look at Strength, Consistency, Specificity, and Temporality criteria with definitions and examples:

Endocarditis II: Clinical Features of Infective Endocarditis

513
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Summary

Mandibular inferior border blunting and limited mouth opening strongly predict the need for computed tomographic (CT) scans in odontogenic infections. These findings can guide imaging decisions in emergency care.

Area of Science:

  • Dentistry
  • Emergency Medicine
  • Radiology

Background:

  • Odontogenic infections are frequent in emergency departments, causing significant healthcare costs.
  • Current guidelines for initial patient evaluation are lacking.
  • Evidence-based criteria are needed to optimize computed tomographic (CT) imaging use.

Purpose of the Study:

  • To derive evidence-based guidelines for CT imaging in odontogenic infections.
  • To identify predictors for CT scan necessity in managing these infections.

Main Methods:

  • Prospective cohort study of 129 patients with odontogenic infections.
  • Classification and regression tree analysis and logistic regression used.
  • Predictor variables included demographics, history, examination, and labs; outcome was CT need.

Main Results:

  • Mandibular inferior border blunting and mouth opening < 25 mm accurately predicted CT need (96.9%).
  • Logistic regression identified these plus odynophagia, floor of mouth induration, and WBC count as relevant predictors.
  • Commonly involved fascial spaces included vestibular and submandibular.

Conclusions:

  • Physical exam findings of mandibular inferior border blunting and restricted mouth opening are key indicators for CT imaging.
  • These criteria can aid in judicious CT utilization for odontogenic infections.
  • Further validation in multicenter studies is recommended.
