Pak J Med Health Sci Jan ;13(4):1320-1.

Aim : To determine the accuracy of Computed Tomography for diagnosing small pulmonary nodules by using maximum intensity projection ( MIP ) images and volume rendering (VR). Study Design: Observational Place and Duration: Dept. of Radiology, Sughra Shafi Medical Complex Narowal from 1-7-2018 to 31 -12 -2018. Methods: Forty patients whom had pulmonary metastasis of both genders had ages of 20 to 55 years been included. All patients had pulmonary metastasis. All images were examined as count of nodules, expert radiologist interpreted all images. Distributions of pulmonary nodules were recorded according to volume rendering (VR) and maximum intensity projection (MIP) by expertise. Results: There were 30(80%) male patients while rest 10 (20%) were females . Four (10%) patients were aged between 20 to 30 years, 8(20%) patients had an age between 31 to 40 years while rest 20 70% were ages > 40 years. Total 445 nodules were diagnosed by computed tomography on maximum intensity projection images, out of them 356(80%) were observed by volume rendering while rest 89(20%) were not diagnosed. On central 209(46.97%) nodules were diagnosed by maximum intensity projection and on peripheral 236 were diagnosed by using maximum intensity projection (P< 0.001 ). Conclusion: Maximum intensity projection imaging technique is more beneficial/useful for diagnosing of small pulmonary nodules as compare to volume rendering.
