Summary
Multimodality imaging is key for thoracic malignancy. [18F]-2-fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET)/CT is increasingly used, offering advantages over PET-only scans for patient evaluation.
Area of Science:
- Radiology
- Nuclear Medicine
- Oncology
Background:
- Multimodality imaging is essential for diagnosing and managing thoracic malignancies.
- Computed Tomography (CT) is a cornerstone for staging and restaging.
- Positron Emission Tomography (PET) and Magnetic Resonance (MR) imaging offer complementary information.
Purpose of the Study:
- To review the role of various imaging modalities in thoracic malignancy.
- To highlight the growing importance of FDG-PET/CT in clinical practice.
- To discuss the potential future applications of PET/MR imaging.
Main Methods:
- Review of current imaging techniques for thoracic cancers.
- Emphasis on the integration of CT and FDG-PET.
- Discussion of the utility of MR imaging and emerging PET/MR.
Main Results:
- CT is central for staging, but FDG-PET/CT enhances diagnostic accuracy.
- [18F]-2-fluoro-2-deoxy-D-glucose (FDG)-PET/CT is becoming the standard, replacing PET-only imaging.
- MR imaging aids in specific staging and characterization scenarios.
Conclusions:
- FDG-PET/CT is a powerful tool in the comprehensive evaluation of thoracic malignancies.
- The combination of modalities optimizes patient management.
- PET/MR imaging may offer future advancements in the field.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

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...
