Computed Tomography

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

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...

Nose and Nasal Cavity

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Lumber Defects

Lumber Defects

Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.
Shakes are minor fractures that run along or across the wood's annual rings, while wane is...

Administering Oxygen by Nasal Cannula

Administering Oxygen by Nasal Cannula

Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Oxygen Delivering System I: Nasal Cannula and Face Mask

Oxygen Delivering System I: Nasal Cannula and Face Mask

The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Summary

This summary is machine-generated.

Postmortem CT scans can identify nasal septum defects, distinguishing between pre-existing conditions and those caused by decomposition or maggot activity. This aids forensic investigations into trauma or cocaine abuse.

Area of Science:

Forensic Pathology
Radiology
Forensic Entomology

Background:

Nasal septum defects have forensic significance, linked to trauma and cocaine abuse.
Decomposition involves maggot infestation, potentially affecting nasal tissues.

Observation:

Five cases (3 early, 2 advanced decomposition) with nasal septum defects were examined using external inspection and postmortem computed tomography (PMCT).
PMCT revealed smoother edges in early decomposition and irregular, maggot-infested edges in advanced decomposition.

Findings:

Postmortem CT effectively detects nasal septum defects.
Radiological appearance of defect edges differentiates pre-existing from postmortem changes.

Implications:

Findings can suggest chronic cocaine abuse, trauma, or other nasal pathologies.
Advanced decomposition can alter or create nasal septum defects, complicating interpretation.
