Arteries of the Head and Neck01:26

Arteries of the Head and Neck

3.2K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Veins of Head and Neck01:19

Veins of Head and Neck

5.6K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

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

8.4K
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...

Quantitative Analysis01:12

Quantitative Analysis

1.4K
Quantitative analysis is a technique for measuring the amount of specific constituents in a sample. When the sample's composition is unknown, qualitative analysis is performed first to identify its components, which ensures that the correct substances are measured during the quantitative phase.
In quantitative analysis, two key measurements are made: the sample quantity and a property proportional to the amount of the analyte (the substance being analyzed). This forms the basis of the...

Sample Handling

2.7K
Transportation of samples from the collection point to the laboratory, as well as storage and preservation techniques, are crucial for maintaining sample integrity and ensuring accurate and reliable test results.
Samples should be transported carefully from collection points to the laboratory. They should be properly sealed and clearly labeled to prevent cross-contamination. To preserve the sample integrity, optimal temperature conditions during transport are essential. This could involve using...

Summary

Radiomics studies in head and neck cancer can include scans with dental filling artifacts by removing affected slices. Bone-related beam-hardening artifacts minimally impact most quantitative image features.

Area of Science:

  • Medical Imaging
  • Radiomics
  • Oncology

Background:

  • Radiomics utilizes quantitative image features for prognostic stratification in head and neck cancer.
  • Artifacts from patient factors, like dental fillings and bone, can impact radiomics feature values.
  • The effect of these specific artifacts on radiomics robustness is not well-understood.

Purpose of the Study:

  • To evaluate the impact of streak artifacts (dental fillings) and beam-hardening artifacts (bone) on head and neck cancer radiomics.
  • To assess methods for artifact compensation in computed tomography (CT) radiomics.

Main Methods:

  • Assessed streak artifact impact by removing portions of the gross tumor volume (GTV) in 30 head and neck cancer patient CT scans.
  • Compared feature value ranges to inter-patient variability.
  • Evaluated beam-hardening artifacts using a phantom with varying material rods (simulating water and bone).

Main Results:

  • Most radiomics features remained robust even when up to 50% of the GTV was removed.
  • Beam-hardening artifacts from bone-simulating material showed minimal significant differences in most feature values compared to water-simulating material.
  • Observed differences in feature values due to beam hardening did not exceed inter-patient standard deviation in most cases.

Conclusions:

  • Removing CT slices with streak artifacts allows scans to be included in radiomics studies.
  • Beam-hardening artifacts from bone do not significantly affect most radiomics features, enabling contouring near bone.
