Summary
Imaging head and neck infections requires both CT and MRI for comprehensive assessment. Advanced techniques like diffusion-weighted imaging and dual-energy CT enhance diagnosis and treatment monitoring.
Area of Science:
- Radiology
- Medical Imaging
- Head and Neck Surgery
Background:
- Head and neck infections necessitate accurate imaging for treatment and prognosis.
- Contrast-enhanced CT is standard, but MRI offers superior characterization of complex cases.
Purpose of the Study:
- To outline a region-based approach for imaging head and neck infections.
- To highlight the complementary roles of conventional and advanced imaging techniques.
Main Methods:
- Review of conventional (CT, MRI) and advanced imaging modalities.
- Discussion of specific techniques: diffusion-weighted imaging, dynamic contrast-enhanced MRI perfusion, MR bone imaging, dual-energy CT, and subtraction CT.
Main Results:
- MRI excels in evaluating skull base, intracranial spread, osteomyelitis, and differentiating abscesses.
- CT and MRI are both valuable for abscesses and thrombophlebitis.
- Advanced CT and MRI techniques improve artifact reduction, artifact reduction, and assessment of inflammation and bony structures.
Conclusions:
- CT and MRI are complementary for head and neck infection imaging.
- Advanced imaging techniques offer significant benefits for diagnosis, characterization, and treatment response evaluation.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

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...

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
