... Radiology program directors have encouraged their programs to think of novel ways to brand themselves in this new virtual world by revamping their online presence [9,10]. Virtual interviews are likely to remain the norm given the financial benefit as well as time saved on travel for applicants [11,12]. Therefore, radiology programs must work on improving their online presence in the COVID-19 era to provide applicants with more thorough information about their future programs to ensure an optimal fit between program and applicant [13]. ...
... 33 Prenatal detection of vertebral anomalies may be difficult unless associated with kyphoscoliosis. 34 Even though most congenital vertebral anomalies are confirmed at approximately the 20th to 28th week of gestation, 34 nearly onethird of the cases are diagnosed postnatally. 35 As the fetal anomaly scan is performed between 18 and 22 weeks of pregnancy in Finland, 36 it is possible that the number of occult vertebral lesions is higher than previously reported. ...
... Both methods inevitably risk skipping qualified applicants who, under different circumstances, might have been admitted to our program and thrived. A recent study showed that without available USMLE Step 1 scores, applicant selection is likely to lean more heavily on Step 2 scores and medical school reputation [1]. This has the potentially harmful effect of discounting exceptional individuals with backgrounds from lower socioeconomic resources. ...
... One of the main challenges to virtual interviewing is the limited exposure that applicants have to each program along with its culture and geographic location. In place of in-person interactions, program websites and other online resources have increased in importance in describing the resident experience to applicants and their decision making for program ranking (9,13). Departmental websites vary widely in the level of information they provide (14À17). ...
... Recently, in a study of brain malformations in primarily discordant monozygotic and dizygotic twins for whom no known genetic or infectious etiology was identified, disruption of vascular perfusion was hypothesized to be the most likely cause (Park et al., 2020). These included malformations of cortical development such as polymicrogyria, periventricular nodular heterotopia, and absent septum pellucidum. ...
... Moreover, it has been proved that glycine substitution in MLBR is harmful (35). Specially, the similarities of Caffey disease and CNO, such as a recurrent, remitting course, bone lesions at the same sites, inflammatory changes in bone and adjacent soft tissues, and tubular bones involvement, indicate that both of them may share the same downstream signaling pathway (36). Since the MAF of P793A in patient 6 was less than 0.00052 in the Asian population, and it is predicted to be probably damaging when using a silico analysis algorithm, we think the variant might play a part in the pathogenesis of CNO. ...
... Classic Dandy-Walker malformation has been described as having three imaging criteria: partial or complete absence of the vermis, cystic enlargement of the fourth ventricle, and an enlarged posterior fossa marked by upward displacement of the tentorium and torcular, seen as "torcular-lambdoid inversion" in the postnatal period [53]. Descriptions of vermis size by 2D measurements and vermis rotation, marked by the tegmento-vermian angle, which is measured between the brainstem and vermis, can be used to describe patients along the continuum on fetal MRI [54]. On fetal MRI a tegmento-vermian angle of ≥80 • can potentially be used to aid in the diagnosis of classic Dandy-Walker malformation [55]. ...
... Although most clinical fetal imaging was performed till recently on 1.5 T scanners, there has been a migration to 3.0 T scanners over time [3,4]. 3.0 T scanners pose improved anatomical delineation with an increased signalto-noise ratio. ...
... Visual aids are recommended and have become a norm. 5 Review of available literature suggests that visual aids decrease the time of presentation, increase interest, improve comprehension, retention, and acceptance. However, it has also been noted that despite the easy availability of tools for creating such visual aids, the quality of these presentations has been deteriorating. ...
... 2,3 Although traditional approaches, including chemotherapy, surgical resection, and transplantation, remain the most common and effective treatment options for HB and have greatly progressed in the past 20 years, the prognosis of patients with clinically advanced HB has not improved. 2,3 Currently, the lack of effective biomarkers for early HB diagnosis greatly limits the treatment of HB. 4 Therefore, it is essential to screen effective biomarkers for the early diagnosis and treatment of HB. ...
