Abstract:
Recent studies indicate a concerning rise in the incidence of pelvic tumors among younger adults [1,2]. Imaging techniques such as ultrasonography, computer tomography (CT), and magnetic resonance imaging (MRI) play a crucial role in the early detection and characterization of these tumors. Ultrasound is commonly the first-line imaging modality for pelvic mass evaluation, particularly in women. However in certain cases, its diagnostic performance may be limited by poor acoustic windows and restricted depth penetration. Similarly, while CT can help with pelvic examination, the limited soft-tissue contrast may make it difficult to differentiate complex structures.
Magnetic resonance imaging (MRI), offering superior contrast resolution and tissue characterization, serves not only as a valuable alternative tool for ultrasonography and CT but also as a primary diagnostic modality in certain cases [3].
This study explores the role of various MRI sequences in characterizing pelvic lesions, focusing on the physical principles underlying tissue contrast, signal intensity variations, and diffusion properties. Image quality is closely related to the trade-off-parameters, spatial resolution, signal-to-noise ratio and total scan time. Balancing these factors can be challenging but understanding the physical principles and their applicable limits can aid in their optimal use. These aspects are important in the characterization of pelvic lesions where the appropriate selection of sequences and parameters plays a crucial role in differentiating benign from malignant lesions and establishing an accurate diagnosis.
In conclusion, pelvic masses can be difficult to diagnose, but MRI is an important tool which can give to radiologists the key they need to overcome this difficulty because of its higher contrast resolution, anatomic detail, and tissue characterization. The understanding of how parameters and sequences influence the quality of acquired images, as well as an integrated medical perspective, contribute to the enhancement of diagnostic and clinical management of pelvic lesions.
