Purpose: We wanted to evaluate the normal glenoid size of Koreans in their 7th and 8th decades by conducting Computed tomographic (CT) studies. Materials and Methods: The CT images were obtained from the normal scapulae of the patients (mean age: 68.8) who had humeral fracture. A display workstation version 2.0.73.315 was used to measure the scans to determine the maximal superoinferior (SI) and anteroposterior (AP) diameters of the glenoid vault. Results: The average diameters of curvature of the glenoid were 31.2 mm (range: 27 to 34 mm) in the superior-inferior direction and 26.1mm (range: 22 to 31mm) in the anterior-posterior direction. Conclusion: This study showed the normal glenoid size of Koreans and it is different from the size that the international literature reported. It should be an important factor for the treatment of fracture or in designing arthroplasty implants.

Liver size is an important component in the diagnosis and follow-up of diffuse liver disease when testing for liver disease using ultrasonography. However, difficulties lies in determining the presence of hepatomegaly and liver atrophy because the method used for measuring liver size differs from one examiner to another and there is no relevant standard based on body build. The present study aims to propose a more objective method for liver size measurement and a reference range based on body build. A total of 260 normal adults (130 males, 130 females) participated in the study. Ultrasonography was performed in all participants to measure the size of the right lobe, left lobe, quadrate lobe, and caudate lobe of liver. Based on Physique Index(PI), a value derived from multiplying weight(kg) by height($m^2$), size of physique was divided into three groups including Group I with PI<150, Group II with $150{\leq}PI{\leq}250$, and Group III with PI>250. Thus, mean liver size by PI and a reference range with 95% reliability were suggested. The superoinferior diameter of right lobe was $12.34{\pm}1.18cm$ in males and $11.07{\pm}0.93cm$ in females, and its reference range was 10.64~11.0cm for Group I, 11.78~12.12cm for Group II, and 13.02~13.84cm for Group III. The anteroposterior diameter(T) of left lobe was $5.93{\pm}1.09cm$ in males and $5.18{\pm}0.99cm$ in females, and its reference range was 4.77~5.17cm for Group I, 5.49~5.79cm for Group II, and 6.68~7.44cm for Group III. The transverse diameter was $3.51{\pm}0.60cm$ in male participants and $3.42{\pm}0.49cm$ in female participants and its reference range was 3.29~3.51cm for Group I, 3.36~3.55cm for Group II, and 3.52~4.0cm for Group III. The caudate lobe index was $11.65{\pm}2.88cm^2$ in males and $9.62{\pm}2.18cm^2$ in females and its reference range was $8.83{\sim}9.75cm^2$ for Group I, $10.62{\sim}11.47cm^2$ for Group II, and $11.89{\sim}14.26cm^2$ for Group III. As a basic measurement method of liver size, the present study suggests measuring the superoinferior diameter for right liver lobe, the anteroposterior diameter for left liver lobe, the transverse diameter for quadrate lobe, and the caudate lobe index for caudate lobe. It is expected that this method along with its relevant reference range can be used as useful indicators in determining hepatomegaly and liver atrophy upon the diagnosis and follow-up testing of diffuse liver disease.

The aim of this study was to establish the diagnostic criteria of normal submandibular glands in adults. Materials included 132 sialograms of selected person from 23 to 28 years of age. In subjects each variable was measured and evaluated statistically introducing 18 items respectively. Conclusions from this study were as follows. 1. The mean diameter of main duct was 1.96㎜ in distal end and 2.71㎜ in hilar end, so the diameter of distal end was smaller than that of hilar end in submandibular glands. 2. The mean length of main duct was 42.02㎜ in submandibular glands. 3. The mean angle of main duct was 35.67 degrees with inferior border of mandible and 103.05 degrees at posterior mylohyoid portion. 4. In configurations following shape of main duct, those revealed that 39.39% of cases of the curvilinear type, 16.67% of cases of the linear type, 22.73% of cases of the sigmiod type and 21.21% of cases of the angular type. And in configurations following course of main duct, those revealed that 83.33% of cases of the smooth type and 16.67% of cases of the tortuous type. 5. The mean caliber of submandibular glands was 45.59㎜ in superoinferior height, 43.56㎜ in anteroposterior width, 28.85㎜ in mediolateral width and 33.65㎜ in extent below mandibular angle. 6. Well-delineated acinar parenchyme was observed in 77.28% of cases and well-defined tertiary ducts in 50.06% of cases. 7. There were no differences between right and left submandibular glands in size and shape of main duct and parenchymal portion, but there were great variations in each individual.
