Modern trends in lipomodeling

“…Three-dimensional photography has gained popularity because of its speed and accessibility [58], [59]. However, this technique is clearly inferior to MRI because of its lower accuracy [60], [61], [62], [63]. …”

Volumetric changes of the pedicled transverse rectus abdominis musculocutaneous flap and the contralateral native breast during long-term follow-up

“…Measuring the volume of a flap after reconstruction is not very simple, since the water displacement technique using Archimedes' principle is not an option. Volume measurements utilizing image modalities are generally simpler and less time-consuming than direct measurements such as casting or measuring devices [9][10][11][12][13][14]. We manually traced two-dimensional PET-CT images taken for oncologic follow-up purposes and used the average of three mea-surements.…”

Estimation of DIEP flap weight for breast reconstruction by the pinch test

“…Nanidis et al () calculated DIEP flap volume using CT angiographic images based on a DIEP flap shape resembling an isosceles triangular prism. Magnetic resonance images have also been used for volume estimation (Kim et al, ). However, all these methods necessitate specialized software or procedures in addition to radiologic images; moreover, estimations are impossible when radiologic exams cannot be performed either due to financial or equipment limitations.…”

“…Surgical planning of DIEP flap based on preoperative estimation of the volume of the abdominal flap has been shown to reduce perfusion‐related complications (Lee & Mun, ) and donor site complications by avoiding elevation of excessively large flaps (Woo, Kim, Lee, & Mun, ). Various methods have been developed for estimating DIEP flap volume based on CT angiography or MR angiography (Eder et al, ; Kim et al, ; Nanidis, Ridha, & Jallali, ; Rosson et al, ; Sotsuka, Fujikawa, & Izumi, ; Tomita, Yano, Hata, Nishibayashi, & Hosokawa, ). When radiologic images are not available, however, these estimation methods cannot be used.…”
