“…Despite many articles reporting on LVA to date, preoperative examinations vary by surgeon preferences and may include ICG lymphography, ultrasound, lymphoscintigraphy, or magnetic resonance imaging (Garza & Chang, 2018; Hara & Mihara, 2017; Hara & Mihara, 2019a; Hara & Mihara, 2019b; Koshima et al, 2000; Mazzei et al, 2017; Mihara, Hara, & Kawakami, 2018; Mihara, Hara, Kawakami, Zhou, et al, 2018; Phillips, Gore, Ramsden, & Furniss, 2019). In the current study, we applied multi‐lymphosome ICG lymphography to detect the lymphatic vessels.…”

“…Preoperative examinations for LVA have recently made progresses, making it possible to identify functional lymphatic vessels in cases of advanced‐stage lymphedema (Hara & Mihara, 2017; Hara & Mihara, 2019a; Mazzei et al, 2017; Mihara et al, 2018; Mihara, Hara, & Kawakami, 2018). In the current study, we evaluated the surgical results of LVA in advanced‐stage lymphedema patients (lymphoscintigraphic type 4 and 5).…”

Background Early‐stage lymphedema patients are said to be candidates for lymphaticovenous anastomosis (LVA). The progressions in the preoperative examinations have made it possible to find the suitable lymphatic vessels even in advanced‐stage lymphedema. The aim of this study was to elucidate the surgical effect of LVA in cases of advanced‐stage lymphedema. Methods We evaluated 42 limbs of 34 patients with lymphoscintigraphic type 4 or 5. A mean disease duration was 7.5 ± 6.5 years. We performed multi‐lymphosome indocyanine green (ICG) lymphography preoperatively to detect the saphenous lymphatics, the lateral calf lymphatics, and the lateral thigh lymphatics. We also performed ultrasound to detect the subcutaneous veins and the dilated lymphatic vessels. The pre‐ and postoperative evaluation was made by the sum of circumference measurements at 6 points per limb. Results The mean number of anastomosis per limb was 2.8 (range, 1–5). Of the 41 limbs for which we performed ICG lymphography, we found the saphenous lymphatics in 29 limbs (70.7%), lateral calf lymphatics in 28 limbs (68.3%), and lateral thigh lymphatics in 21 limbs (51.2%). We found at least 1 linear pattern in ICG lymphography for 39 limbs (95.1%). The mean pre‐ and postoperative circumference (sum of 6 points) were 221.7 ± 4.9 cm and 215.9 ± 4.9 cm, which was significantly reduced (p < .01). Conclusions LVA was effective for advanced‐stage lymphedema patients. An adequate preoperative examination with plural imaging methods seems helpful for achieving a successful surgical result.

“…As previously discussed, the sensitivity of breast MRI for the detection of breast cancer is high, but its specificity is only moderate, ranging from 37% to 100% [ 16 ]. It is then essential to biopsy suspicious MR-detected lesions to make a definitive diagnosis [ 22 ]; MR-guided breast biopsy is gradually increasing, especially when lesions are visible on MRI but not on conventional imaging [ 41 – 43 ]. Nevertheless, these techniques are not widely available and require the use of expensive MR magnets, time, and personnel [ 21 ].…”

Contrast enhanced magnetic resonance imaging (CE-MRI) has acquired a central role in the field of diagnosis and evaluation of breast cancer due to its high sensitivity; on the other hand, MRI has shown a variable specificity because of the wide overlap between the imaging features of benign and malignant lesions. Therefore, when an additional breast lesion is identified at CE-MRI, a second look with targeted US is generally performed because it provides additional information to further characterise the target lesion and makes it possible to perform US-guided biopsies which are costless and more comfortable for patients compared with MRI-guided ones. Nevertheless, there is not always a correspondence between CE-MR findings and targeted US due to several factors including different operator's experience and position of patients. A new technique has recently been developed in order to overcome these limitations: US with MR coregistration, which can synchronise a sonography image and the MR image with multiplanar reconstruction (MPR) of the same section in real time. The aim of our study is to review the literature concerning the second look performed with this emerging and promising technique, showing both advantages and limitations in comparison with conventional targeted US.

“…MRI should be performed for characterizing a thymic lesion only in selected cases, such as the distinction between a small thymic neoplasm and an atypical thymic hyperplasia, exploiting dual gradient-echo in-phase and opposed-phase sequences. MR lymphangiography may be used in the suspicion of a lesion of lymphatic origin (69)(70)(71)(72)(73).…”

Dual energy CT (DECT)with image acquisition at two different photon X-ray levels allows the characterization of a specific tissue or material/elements, the extrapolation of virtual unenhanced and monoenergetic images, and the quantification of iodine uptake; such special capabilities make the DECT the perfect technique to support oncological imaging for tumor detection and characterization and treatment monitoring, while concurrently reducing the dose of radiation and iodine and improving the metal artifact reduction. Even though its potential in the field of oncology has not been fully explored yet, DECT is already widely used today thanks to the availability of different CT technologies, such as dual-source, singlesource rapid-switching, single-source sequential, single-source twin-beam and dual-layer technologies.Moreover DECT technology represents the future of the imaging innovation and it is subject to ongoing development that increase according its clinical potentiality, in particular in the field of oncology. This review points out recent state-of-the-art in DECT applications in gland tumors, with special focus on its potential uses in the field of oncological imaging of endocrine and exocrine glands.
