Spleen is a reticulo-endothelial and lymphoid organ and sometimes works as hematopoietic organ. Otherwise this organ is cemetery of RBCs. Spleen is enlarged in assorted clinical upsets e.g. infection, metamorphosis or storage upset and haematological abnormalities1,2. Spleen is ne'er tangible boulder clay it is enlarged two-three times of its ain size3. There are many manners of probe to place the hypertrophied spleen e.g.-plane radiogram, echography, computed imaging, MRI and radionuclide scan. Out of these modes echography and computed imaging are most dependable for intra-abdominal organs4. Assorted surveies were done by echography to analyze the additive dimension of spleen-length, breadth, and thickness. But CT-based additive dimension are still unavailable. Unfortunately, dimensions determined by 2-D USG are limited preponderantly by the variable, irragular contour of lien but besides by the trouble in wholly scanning the full organ or visualising complete contours as a consequence of the presence of overlying constructions such as bone, intestine gas or kidney5. CT imagination is more accurate than echography because this drawback doesnot occur with computed tomography6, 7, 8.
CT scans of 126 patients ( 72 male and 54 female ) were used to mensurate the volume of lien. The age of patients ranged from 20 to 70 years ( 50.33±18.9yrs ) ( Table-I ) . The information was collected from December 2006 to April 2007 with permission of Department of Radio-diagnosis, KGMU Lucknow and informed consent taken from each patient. CT scans were obtained for assorted clinical indicants and followup of abdominal injury, abdominal hurting and to except an abdominal mass or adenopathy. The patient 's organic structure weight and tallness at or near the clip of the CT scrutiny were recorded. Spleen axial and transverse sectional image were obtained a CT Helical instrument. The proficient parametric quantities were 120 kv potency, 120 ma current, 10mm piece breadth with indistinguishable Reconstruction index and a rotary motion clip of 1.5 secs. The medical records of all patients were reviewed. Patients whose liens appeared unnatural on CT scans were excluded. Additionally, any patients who had clinical, biochemical or imaging grounds of conditions that could impact the size of the lien, haematological upsets, abdominal malignances, infection and portal high blood pressure, splenetic injury, cyst, and auto-immune diseases were excluded from the survey.
CT-scan dicom images of each patient were opened in Able-3D-doctor package. Spleen is identified in each cross subdivision and longitudinal subdivision of CT-scan images. The length of lien recorded in longitudinal subdivision along 10th rib in cephalo-caudal way ( figure-1 ) . Width of lien besides recorded in longitudinal way ( figure-2 ) but thickness measured in cross-section image ( figure 3 ) . All dimensions were recorded maximal appreciated in subdivisions for better truth.
All statistics were generated by SPSS version 10.The pupil T-test was used for comparing of agencies. P & A ; lt ; 0.05 was considered important for comparing of agencies and for arrested development analysis. Association between splenetic dimensions and physical criterions of patients was assessed with the Pearson correlativity coefficient ; to place the exact form of relationship, non-linear arrested development every bit good as additive arrested development was applied. Multiple arrested development analysis was applied in backward stepwise manner to prove the independent consequence of all physical criterions on splenetic parametric quantities.
Frank et Al used conventional echography to measure 793 healthy patients ( 17-82yrs. ) and found that 95 % of patients had splenetic length & A ; lt ; 11cm, breadth & A ; lt ; 7cm and thickness & A ; lt ; 5cm9. Niederau et al studied 915 healthy topics utilizing echography and found that average longitudinal and cross diameter of lien to be 5.8±1.8 centimeter and 5.5±1.4 centimeter severally. These dimensions were much smaller than other surveies because writer did non mensurate maximal dimension10. Picardi et Al. found average longitudinal dimension of spleen ranged from 8 to 11 centimeter ( average: 9.5 centimeter ) 11. Mittal et Al. performed pilot survey of normal measuring of spleen by echography on Rajasthani population and found mean length of spleen 9.40±0.91 centimeter in males and 9.34±0.95 centimeter in females12. In older topics they found average length of spleen 9.64±0.64 centimeter. Spielmann et Al, mean length of lien was found to be 11.4±1.7 centimeter in males and 10.3±1.3 centimeter in females13. Konus et Al. found average longitudinal dimension: 10.1±1.03 cm13. In our survey intend splenetic length in North Indian population was 10.67±1.62 centimeter ( female: 10.34±1.58 and male 10.91±1.67 centimeter, P & A ; gt ; 0.05 ) 14. Mittal et Al. measured mean breadth of lien in male every bit good as female 3.45±0.59 centimeter and 3.59±0.55 centimeter. Average breadth of lien measured by Spielmann was 5.0±0.8 in males and 4.2±0.7 centimeter in females. In our survey average breadth of spleen 8.61±1.58 centimeter ( male: 9.74±1.62 centimeter and female 9.26±1.66 centimeter, P & A ; gt ; 0.05 ) and average thickness of spleen 4.86±1.22cm ( female: 4.70±1.19 centimeter and male: 4.97±1.29 centimeter, P & A ; gt ; 0.05 ) .These all dimension of spleen best correlated with tallness of the patients ( scatter plot-1.1, 1.2, 1.3 ) . Age of individual had important negative correlativity with cephalo-caudal length of spleen but rest of splenetic dimension did non hold important correlativity with age ( scatter plot-1.4, 1.5, 1.6 ) .
