Computed tomography and magnetic resonance imaging: past, present and future

Area of Science:

• Radiology
• Medical Imaging
• Pulmonology

Background:

• Computed tomography (CT) and magnetic resonance imaging (MRI) are crucial diagnostic tools in chest imaging.
• Advancements in CT technology, including high-resolution CT (HRCT) and spiral CT, have significantly improved diagnostic capabilities.
• MRI offers unique advantages in evaluating soft tissues and vascular structures due to its multi-parametric signal characteristics.

Purpose of the Study:

• To summarize current recommendations for chest CT and MRI use.
• To explore future developments in thoracic imaging techniques.
• To highlight the diagnostic performance of advanced CT and MRI in various chest pathologies.

Main Methods:

• Review of current literature and clinical guidelines for CT and MRI in chest imaging.
• Description of technological advancements in CT, such as HRCT, spiral CT, and multidetector CT.
• Explanation of MRI principles and its application in chest imaging, including magnetic resonance angiography.

Main Results:

• HRCT demonstrates high sensitivity and specificity for focal and diffuse lung diseases, correlating well with pathology.
• Spiral and multidetector CT enhance imaging of airways, vessels, and nodules, with spiral CT becoming the standard for pulmonary embolism diagnosis.
• MRI is effective for evaluating the heart, major vessels, mediastinum, and hilar structures, with magnetic resonance angiography showing promise for pulmonary embolism diagnosis.

Conclusions:

• Advanced CT techniques, particularly HRCT and spiral CT, are indispensable for diagnosing a wide range of chest conditions.
• MRI provides complementary information, especially for soft tissue and vascular assessments, and is a promising tool for pulmonary embolism.
• Future developments in both CT and MRI promise further enhancements in chest imaging accuracy and scope.
