... ROC, receiver operating characteristic; PD, proton density; NPC, nasopharyngeal carcinoma; OC, occipital clivus lesions. Ghosh et al. [46] proved that neuroblastomas with MYCN amplification had higher signal intensities (Mean and Maximum) and Energy on ADC map than tumours without MYCN amplification. Zhao et al. [47] also revealed that rectal cancer with lymph node metastasis had both a higher signal intensity (Maximum of the T2 and PD maps) and Energy than cancer without lymph node metastasis. ...

... In addition, for disease staging, a thorough history and physical examination including radiologic imaging is required: chest radiograph for pulmonary disease, complete radiographic skeletal survey for assessment of osseous disease, and abdominal ultrasound for evaluation of liver and/or spleen involvement (10). Recent efforts have tried to conduct required clinical evaluation with one single imaging exam (11). Several investigators reported that magnetic resonance imaging (MRI) has a higher sensitivity for the detection of LCH lesions compared to skeletal surveys (12,13). ...

... A few studies have proposed different DL solutions to the PBT segmentation problem, with whole tumor Dice scores ranging between 0.68-0.76 [17][18][19][20] . These approaches show lower performance than the models proposed for adult brain tumor segmentation, are often only designed for a particular histology, only segment the whole tumor without subregions, or segment the tumors based on one or two MRI sequences. ...

... The manual examination of cancerous images is cost-ineffective due to costly equipment and sometimes results in erroneous results due to the mishandling of details. Machine learning (ML) is now frequently used in cancer research as it provides an easy way to perform data analysis and automated extraction of important information from the data [8]. ...

... These same students have a high dropout rate, lack mentors, and lack knowledge about the variety of careers available to them [17]. Lack of mentorship has been cited as a major contributing factor for the underrepresentation of Black trainees within the field of radiology [18]. ...

... Furthermore, Koshy et al (11) pointed out that FNAB can identify pNT well. Research has also proved the important role FNAB plays in recurrent NB and in guiding clinical surgery and treatment of pediatric solid abdominal tumors (12,13). In this paper, the sensitivity and speci city of biopsy were 88.9% and 100%, respectively, as expected for surgery. ...

... A pilot study of lung MRI in children with interstitial lung disease showed MRI to perform well in the detection of consolidation, parenchymal bands and fissural thickening but less well for findings of septal thickening, ground-glass opacity, nodules and cysts as compared to CT [9]. New MRI techniques, including ultrashort echo time (UTE), improve the depiction of the lung parenchymal anatomy [10]. Functional information regarding lung ventilation revealed by hyperpolarized gas MRI in children with cystic fibrosis could be applied to bronchiolitis obliterans and other obstructive lung diseases but is limited by patient cooperation, the lack of availability of hyperpolarized gas, and expertise in performing this technique at most imaging centers [10]. ...

... Deep learning methods for bone tumor analysis have been explored for other imaging modalities than CT, including X-ray [32,[44][45][46], as well as more costly PET-CT [35] and MRI imaging studies [37][38][39][40]. Unlike our joint approach, most of the existing methods focused on either tumor classification [32,37,38,46] or tumor segmentation [35,39,40]. ...

... Several studies reported variable degrees of sensitivity (84.6-100%) and specificity (61.1-88.6%) for the HBS in diagnosing BA [19][20][21][22][23]. In a large metaanalysis discussing the accuracy of 99mTc-IDA HBS in differentiating BA from NH, Kianifar et al. have reported a pooled sensitivity of 98.7% and a pooled specificity of 70.4%; the reported high sensitivity was due to the extremely rare false negative results recorded [24]. ...
