Data Sheet 1_Prenatal MRI features of fetal complete agenesis of the corpus callosum assoc

101 prenatal MRI cases diagnosed with complete agenesis of the corpus callosum, including 16 cases associated with unilateral hemispheric cortical malformation. The retrospective study by Huihui Lin analyzes imaging features like the 'rake sign' and 'garland sign', fetal gender, and gestational age at diagnosis. The dataset was last updated in May 2026.

Use Cases

• Classifying types of unilateral cortical malformation (C1, C4, C5) based on MRI feature descriptions.
• Investigating associations between fetal gender and the occurrence of cACC with cortical malformation.
• Analyzing the distribution of malformation locations (left vs. right hemisphere, frontal/parietal/occipital lobes).
• Studying the gestational age range (23 to 27 weeks) for prenatal diagnosis of this condition.

Strengths

• Includes 101 total cases of fetal complete agenesis of the corpus callosum (cACC) diagnosed via prenatal MRI.
• Provides detailed analysis of 16 specific cases with associated unilateral cortical malformation, including gender breakdown (13 male, 3 female) and gestational age range.
• Documents specific imaging signs ('rake sign', 'garland sign') and classifies malformation types (Type I, II, III) with case counts.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment for specific analyses.
• The dataset's 807.1 KB size suggests a limited scope, likely containing summary or metadata rather than raw image data.
• Description metadata is limited; actual data structure and field semantics must be inferred after download.
