Summary
Diagnosing skull base osteomyelitis (SBO) requires combining anatomical and functional imaging. PET-MRI and high-resolution CT (HRCT) offer complementary strengths for accurate SBO assessment.
Area of Science:
- Radiology
- Nuclear Medicine
- Infectious Diseases
Background:
- Skull base osteomyelitis (SBO) is a challenging infection.
- Accurate diagnosis and monitoring are crucial for effective treatment.
- Current imaging techniques have limitations in fully characterizing SBO.
Purpose of the Study:
- To provide a comprehensive review of current imaging modalities for SBO.
- To evaluate the strengths and weaknesses of each technique.
- To guide optimal imaging strategies for SBO diagnosis and follow-up.
Main Methods:
- Review of computed tomography (CT) and magnetic resonance imaging (MRI) for anatomical detail.
- Assessment of nuclear medicine techniques for functional imaging of infection.
- Evaluation of hybrid imaging modalities like PET-CT and PET-MRI.
Main Results:
- CT and MRI provide essential anatomical information.
- Nuclear techniques are valuable for assessing disease activity.
- Hybrid PET-CT and PET-MRI integrate anatomical and functional imaging capabilities.
Conclusions:
- No single imaging modality is sufficient for comprehensive SBO evaluation.
- A combined approach utilizing both anatomical and functional imaging is recommended.
- For suspected SBO, PET-MRI (including T1, T2, T1-FS-GADO, DWI sequences) and HRCT are suggested for diagnosis and follow-up.

1.5K
Accurate analysis of complex samples often requires advanced preparation techniques to achieve reliable and reproducible results. Samples containing inorganic or organic materials can be challenging to dissolve or decompose effectively. Standard sample preparation methods include acid digestion, fusion, dry ashing, and wet digestion.
Acid digestion with strong acids is commonly used to dissolve inorganic materials that are insoluble (do not dissolve) in water. This method can be useful for...

01:22Sutures of the Skull
13.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

606
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

01:08Overview of the Skull
8.0K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

02:22Overview of Advanced Functional Groups
30.4K
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups

00:56Extraction: Advanced Methods
1.2K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...
