Summary
This summary is machine-generated.Unenhanced multidetector CT (MDCT) effectively detects cocaine-filled packets (CFP) ingested by body stuffers. This imaging technique aids in the rapid medicolegal management of individuals presenting with these packets.
Area Of Science
- Radiology
- Emergency Medicine
- Forensic Science
Background
- Emergency departments encounter rising illegal drug-related health issues.
- Body stuffers ingest or conceal drugs, posing life-threatening risks if packets rupture.
- Unenhanced multidetector CT (MDCT) is explored for detecting ingested cocaine-filled packets (CFP).
Purpose Of The Study
- To evaluate the diagnostic accuracy of unenhanced MDCT for identifying CFP in a simulated body stuffer scenario.
- To assess the reliability of MDCT in detecting both genuine and simulated CFP.
Main Methods
- A phantom model simulating normal bowel contents with mixed true and false CFP was used.
- Four radiologists independently assessed the presence and number of CFP over 18 reading sessions.
- Key performance metrics including sensitivity, specificity, and interobserver agreement were calculated.
Main Results
- High interobserver agreement was observed for detecting any packets (kappa=0.63), true CFP (kappa=0.74), and false CFP (kappa=0.58).
- Overall sensitivity and specificity for detecting any CFP were 95.6% and 100%, respectively.
- Sensitivity for true CFP was 86.5% with 100% specificity; false CFP detection showed 98.1% sensitivity and 65% specificity.
Conclusions
- Unenhanced MDCT without bowel preparation is a reliable imaging modality for rapid CFP detection.
- This technique facilitates the immediate medicolegal management of body stuffers.
- MDCT offers a fast, reproducible method for identifying ingested packets.

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...
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...
The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.
Taste and Salivation: Ingestion is both mechanical and sensory. Taste buds on the tongue detect flavors, triggering brain signals that stimulate salivary glands to produce more saliva. This response is essential for appetite regulation and digestive enzyme secretion.
Role of Teeth in Mastication: Different tooth types have specific roles in mechanical digestion. Incisors cut, canines tear, and...
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...
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.
