“…Krug et al (18) demonstrated that high resolution MR images obtained by a 1.0T system using a microscopy coil with an inner diameter of 75 mm enabled visualization of the dermis, subcutaneous tissue, and muscle fascia allowing for a pattern analysis that may minimize the differential diagnosis of various skin diseases and may help to reduce the number of skin biopsies in certain indications. In a study by Gufler et al (19), high-resolution MRI with a microscopy surface coil and a high-field 1.5-T MR system proved to be a suitable method to determine the extension and depth of infiltration in regards to basal cell carcinomas of the facial region.…”

ObjectiveThe purpose of this study was to evaluate the accuracy of a preoperative MRI with microscopy coils in determining the primary tumor thickness of malignant melanoma with histopathologic correlation.Materials and MethodsEleven patients with histopathologically confirmed malignant melanoma were included in this study. MR images of the tumors were obtained with a 47-mm microscopy coil on 1.5T MR scanners and were evaluated by two radiologists, who assessed the thickness of the primary tumor on T2-weighted images (T2WI) and gadolinium-enhanced T1-weighted images with fat suppression (Gd-T1WI) and compared the results with the histopathologic findings as the reference standard. Correlations between tumor thickness on MRI and histopathologic examination were assessed using concordance correlation coefficients (CCCs). Inter- and intraobserver variabilities of tumor measurements were also assessed by intraclass correlation coefficient (ICC).ResultsAmong the 11 cases included in the study, 10 cases from the same number of patients were managed with surgical excision and one case was confirmed with punch biopsy. The primary tumor thickness measured on T2WI showed better correlation with histopathologic results, as compared with measurements taken on Gd-T1WI: the CCC of measurements on T2WI ranged from 0.64 to 0.78, indicating a substantial agreement, whereas the CCC of measurements on Gd-T1WI ranged from 0.50 to 0.61, indicating a moderate to substantial agreement. Inter- and intraobserver agreements of readers 1 and 2 were excellent for both T2WI and Gd-T1WI, with ICC ranging from 0.86 to 0.99.ConclusionMR imaging with microscopy coils may be an accurate technique in the preoperative assessment of tumor thickness in malignant melanoma, especially on T2-weighted images.

“…Highresolution MRI has been shown to be useful in evaluating bony invasion of carcinomas that fail to be detected in a CT scan. 5,6 With high-risk tumors confined to the soft tissues, MMS is indicated given its visualization of 100% of the surgical margin versus 0.1% to 0.2% visualization with traditional excision and breadloafing. 4,7 Although radical excision of soft tissue BCC has a higher recurrence than with MMS, when there is intracranial invasion, it becomes the criterion standard.…”

“…Among nonoptical approaches, high-frequency ultrasound and microscopic magnetic resonance imaging offer limited resolution but satisfactory imaging depth. 4,5 The optical properties of skin such as scattering and absorption are nonhomogeneous as a result of different refractive indices and absorption coefficients of skin layers and microstructures. These heterogeneous optical properties can be used to create contrast in imaging of the skin.…”

Three-dimensional imaging of normal skin and nonmelanoma skin cancer with cellular resolution using Gabor domain optical coherence microscopy

et al. 2012

Abstract. We investigate morphological differences in three-dimensional (3-D) images with cellular resolution between nonmelanoma skin cancer and normal skin using Gabor domain optical coherence microscopy. As a result, we show for the first time cellular optical coherence images of 3-D features differentiating cancerous skin from normal skin. In addition, in vivo volumetric images of normal skin from different anatomic locations are shown and compared.

High-Resolution MRI of Basal Cell Carcinomas of the Face Using a Microscopy Coil

Abstract: High-resolution MRI using a microscopy surface coil is a promising method to determine the extension of basaliomas of the facial region and to exclude infiltration of bone by the tumor.
