Imaging Techniques for Diagnosing Left Inguinal Hernia
- The diagnosis of inguinal hernias can often be made by clinical examination, but imaging methods are useful in certain situations, such as when the clinical examination is inconclusive or when evaluating the content of the hernia and possible complications 1.
- A systematic review found that ultrasound (US) is more precise than Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) in diagnosing inguinal hernia, with high sensitivity and specificity, although performance is highly dependent on the operator's level of expertise 2.
Ultrasound as a Preferred Imaging Modality
- Ultrasound has emerged as a convenient imaging tool for diagnosing inguinal hernia due to its advantages, such as portability and absence of radiation 3.
- A retrospective study found that ultrasonography has a high sensitivity (97%) and specificity (77%) in diagnosing inguinal hernias, making it suitable for ruling out an inguinal hernia when the findings are negative 4.
- A comparative study found that the sensitivity of ultrasound in diagnosing inguinal hernias is 100% for indirect types and 80% for direct types, with a strong correlation between the size of defects measured by ultrasound and surgery 5.
Comparison of Imaging Modalities
- A systematic review compared the diagnostic accuracy of CT, MRI, and US in diagnosing inguinal hernia and found that US had the highest sensitivity and specificity 2.
- Ultrasound is preferred over CT and MRI due to its convenience, portability, and lack of radiation, making it a suitable imaging modality for diagnosing inguinal hernias 3.
