AI Article Synopsis

  • High-resolution MR imaging using a microscopy coil is an effective method for assessing skin lesions by providing detailed images of dermal structure.
  • This technique helps in accurately identifying the deep margins of skin tumors, which is crucial for planning surgeries, especially Mohs micrographic surgery for complex facial tumors.
  • Basal cell carcinoma, the most common type of skin cancer, often appears on the face, making it important to use microscopy-coil MR imaging to guide surgeons in achieving optimal results while maintaining the patient's appearance.

Article Abstract

High-resolution magnetic resonance (MR) imaging performed with a microscopy coil is a robust radiologic tool for the evaluation of skin lesions. Microscopy-coil MR imaging uses a small surface coil and a 1.5-T or higher MR imaging system. Simple T1- and T2-weighted imaging protocols can be implemented to yield high-quality, high-spatial-resolution images that provide an excellent depiction of dermal anatomy. The primary application of microscopy-coil MR imaging is to delineate the deep margins of skin tumors, thereby providing a preoperative road map for dermatologic surgeons. This information is particularly useful for surgeons who perform Mohs micrographic surgery and in cases of nasofacial neoplasms, where the underlying anatomy is complex. Basal cell carcinoma is the most common nonmelanocytic skin tumor and has a predilection to manifest on the face, where it can be challenging to achieve complete surgical excision while preserving the cosmetic dignity of the patient. Microscopy-coil MR imaging provides dermatologic surgeons with valuable preoperative anatomic information that is not available at conventional clinical examination.

Purpose: This study aimed to assess the performance of 2-dimensional (2D) imaging with microscopy coils in delineating teeth and periodontal tissues compared with conventional 3-dimensional (3D) imaging on a 3 T magnetic resonance imaging (MRI) unit.

Materials And Methods: Twelve healthy participants (4 men and 8 women; mean age: 25.6 years; range: 20-52 years) with no dental symptoms were included.

Article Synopsis
  • Lesion size is crucial for determining treatment and predicting outcomes for osteochondral lesions of the talus (OLTs), yet traditional MRI often over or underestimates sizes compared to surgical measurements.
  • This study compared the accuracy of the surface microscopy coil (SMC) MRI to conventional MRI methods in assessing OLT sizes before surgery, involving 43 patients from 2019 to 2022.
  • Results indicated that SMC measurements were significantly more accurate than those from conventional coils (ASC), with 39 out of 43 SMC assessments aligned with surgical measurements, while only 26 out of 43 from ASC showed consistency.

In the first part of this 2-part series, we described how to implement microscopy coil MR imaging of the orbits. Beyond being a useful anatomic educational tool, microscopy coil MR imaging has valuable applications in clinical practice. By depicting deep tissue tumor extension, which cannot be evaluated clinically, ophthalmic surgeons can minimize the surgical field, preserve normal anatomy when possible, and maximize the accuracy of resection margins.

Background: While uncomplicated cases of skin squamous cell carcinoma (cSCC) can be treated with surgery topical therapy alone, more objective and non-invasive examination methods are needed to guide clinicians to make more detailed biopsy and surgical plans for lesions with atypical or subcutaneous growth. High-resolution magnetic resonance imaging (HR-MRI) is a novel skin imaging method.

Materials And Methods: Prospective collection of 19 patients with clinically suspected cSCC.

Background: The extent and depth of facial nonmelanoma skin cancers and the involvement of adjacent structures are critical features for surgical planning, but they are difficult to assess clinically. High-resolution MRI (HR-MRI) with microscopy coil may facilitate detailed evaluation of skin lesions. The authors performed this prospective study to determine the value of high-resolution microscopy coil MRI in the preoperative evaluation of nonmelanoma skin cancer.
