Objective To determine the early treatment response after microwave ablation (MWA) of inoperable lung neoplasms using the apparent diffusion coefficient (ADC) value calculated 24 h after the ablation. Materials and methods This retrospective study included 47 patients with 68 lung lesions, who underwent percutaneous MWA from January 2008 to December 2017. Evaluation of the lesions was done using MRI including DWI sequence with ADC value calculation pre-ablation and 24 h post-ablation. DWI-MR was performed with b values (50, 400, 800 mm 2 /s). The post-ablation follow-up was performed using chest CT and/or MRI within 24 h following the procedure; after 3, 6, 9, and 12 months; and every 6 months onwards to determine the local tumor response. The post-ablation ADC value changes were compared to the end response of the lesions. Results Forty-seven patients (mean age: 63.8 ± 14.2 years, 25 women) with 68 lesions having a mean tumor size of 1.5 ± 0.9 cm (range: 0.7–5 cm) were evaluated. Sixty-one lesions (89.7%) showed a complete treatment response, and the remaining 7 lesions (10.3%) showed a local progression (residual activity). There was a statistically significant difference regarding the ADC value measured 24 h after the ablation between the responding (1.7 ± 0.3 × 10 −3 mm 2 /s) and non-responding groups (1.4 ± 0.3 × 10 −3 mm 2 /s) with significantly higher values in the responding group ( p = 0.001). A suggested ADC cut-off value of 1.42 could be used as a reference point for the post-ablation response prediction (sensitivity: 66.67%, specificity: 84.21%, PPV: 66.7%, and NPV: 84.2%). No significant difference was reported regarding the ADC value performed before the ablation as a factor for the prognosis of treatment response ( p = 0.86). Conclusion ADC value assessment following ablation may allow the early prediction of treatment efficacy after MWA of inoperable lung neoplasms. Key Points • ADC value calculated 24 h post-treatment may allow the early prediction of MWA efficacy as a treatment of pulmonary tumors and can be used in the early immediate post-ablation imaging follow-up. • The pre-treatment ADC value of lung neoplasms is not different between the responding and non-responding tumors.

Children with cerebral palsy (CP) have limited postural control and functional ability. TheraTogs was reported to improve postural stability. However, studies involving the functional ability and quality of life are limited. We aimed to investigate the effects of TheraTogs use as an orthotic garment and strapping system on the balance and functional ability of children with spastic diplegic CP and if wearing TheraTogs improves their quality of life. A total of 34 children (aged 5-8 years) with spastic diplegic cerebral palsy participated in this study. The control group received conventional physical therapy (CPT), whereas the study group received CPT in addition to wearing TheraTogs. Balance, lower limb strength, and functional abilities were examined using the Biodex balance system, 30-s chair rise test, and Pediatric Evaluation of Disability Inventory-PEDI). The measured parameters of postural stability significantly improved in both groups post-treatment (p<0.05). The study group showed significant improvement in balance and lower limb strength compared to the traditional physical therapy group (p < 0.05). Both groups showed significant improvement in functional skill mobility (0.001 and 0.01 for control and study groups respectively) and caregiver assistance mobility scores (p=0.001 and <0.001 for control and study groups respectively); however, there was no significant improvement in self-care ability with TheraTogs. The 30s sit-to-stand showed increased number of sit to stands in both groups post treatment (p=<0.001 for both groups) and the study group showed significant improvement compared to the control group (p=0.01). The findings in this study suggest that both conventional physical therapy and TheraTogs are beneficial in improving balance and functional ability. TheraTogs could be utilized as a useful posture orthosis to help improve the balance and functional strength of children with spastic diplegic cerebral, palsy indicating improved quality of life.
