Background: Carcinoma pancreas is being diagnosed increasingly with the help of conventional imaging like ultrasonography (USG), computerized tomography (CT) scan and magnetic resonance imaging (MRI).Imaging also gives the opportunity to assess resectability. In our country MRI and CT scan are not widely available and most of the pancreatic carcinoma is too advanced for curative surgical resection when diagnosed. These are unresectable carcinoma pancreas (UCP). Objectives: To evaluate the efficacy of imaging in diagnosing carcinoma pancreas and to assess resectability after comparing them with peroperative findings. Methods: This retrospective study was carried out in the department of Hepato-Biliary-Pancreatic Surgery in Bangladesh Institute for Research and Rehabilitation in Diabetic Endocrine and Metabolic disorders (BIRDEM) hospital, Dhaka, Bangladesh from July 2004 to June 2006 (2 years). After laparotomy findings and histopathological confirmation 50 patients were labeled as UCP. Among 50 patients male were 28 & female patients were 22. Imaging modalities used before surgery was assessed and compared with per operative findings. USG were done in all patients and CTscan in 45 patients. MRI was done in 08 patients suspected clinically as pancreatic carcinoma where USG /CT scan had failed to reach a conclusion. Findings of the various imaging studies regarding diagnosis and unresectability were compared with per operative findings. Results: USG was able to diagnose 42 (84%) pancreatic carcinoma patients with unresectibility in 29 (69%). Forty five patients (90%) were diagnosed by CT scan and could label 38 (84.44%) as unresectable. MRI was 100% accurate to diagnose and label the entire 08 patient as unresectable carcinoma pancreas. Cumulative multimodal preoperative imaging was 91.33% accurate in diagnosing carcinoma pancreas and could tell the features of unresectibility in 73.59% patients. Conclusion: CT scan should be the primary imaging modality for diagnosing pancreatic carcinoma and its resectability. MRI is very promising for diagnosing and assessing UCP. Multimodal imaging is better than single imaging. Chattagram Maa-O-Shishu Hospital Medical College Journal Volume 12, Issue 3, September 2013: 23-26

Despite the extensive attention attracted by magnetic resonance imaging (MRI) in the radiation therapy, computed tomography was reintroduced by the researchers. During the calculation process of the 3D dose distribution of tissues, there were some arguments about the electron density information obtained from the CT scan. However, the CT-provided bones are accurate for constructing a radiograph. Recently, the advantages boosted by the soft tissue contrast relying on MRI and as well as the advantages boosted by CT imaging have been combined by the using of MRI/CT. Unfortunately, disadvantages still exist in the MRI/CT workflow because the voxel-intensities are unbalanced in the MRI and the CT scan. Here, based on the mapping method of CT and MRI, the potential of pseudo-CT (PCT) instead of CT planning was studied. The estimated PCT only from the corresponding MRI was obtained by using the patch-based random forest regression. The CT voxel target was trained by 3D Gabor feature in the MRI cube and the Local Binary Pattern (LBP). Besides, the regression task was solved by the alternative regression forest. According to the experiment, the method performs better than the current dictionary learning-based (DLB) method or atlas-based (AB) method.

Abstrak Spondilitis tuberkulosis (TB) atau Pott’s disease adalah infeksi tulang belakang yang disebabkan Mycobacterium tuberculosis akibat TB ekstrapulmoner. Penyakit ini tergantung berbagai faktor seperti usia, status gizi, dan penyakit penyerta. Penelitian deskriptif ini dilakuakn untuk mengetahui Profil pasien spondilitis tuberkulosis di Rumah Sakit Pusat Angkatan Darat (RSPAD) Gatot Soebroto. Data diperoleh dari rekam medis sebanyak 75 sampel. Penelitian ini menunjukkan jenis kelamin laki – laki (50,7%), kelompok usia 21 – 29 tahun (29,3%), dan status gizi normal (33,3%) merupakan kelompok yang terbanyak terkena spondilitis tuberkulosis (TB). Jenis pekerjaan terbanyak merupakan ibu rumah tangga (28,0%). Sebanyak 69 pasien (92%) tidak memiliki riwayat merokok dan semua pasien tidak memiliki riwayat mengonsumsi alkohol. Hanya 1 orang pasien spondilitis TB yang memiliki hasil basil tahan asam (BTA) positif. Sebanyak 41 orang (54,7%) pasien spondilitis TB didiagnosis melalui Magnetic Resonance Imaging/ Computerized Tomographic Scan (MRI/CT SCAN) dengan lesi spondilitis TB terbanyak terdapat pada torakal. Kemampuan MRI mendiagnosis lebih baik dibandingkan PCR dan BTA.   Kata kunci: Status Gizi, Torakal, Basil Tahan Asam   The Profile of Tuberculosis Spondylitis patients (Pott's Disease) at Rumah Sakit Pusat Angkatan Darat Gatot Soebroto   Abstract Tuberculous spondylitis (TB) or Pott's disease is a spinal infection caused by Mycobacterium tuberculosis due to extrapulmonary TB. This disease depends on various factors such as age, nutritional status, and comorbidities. This descriptive study was conducted to determine the profile of tuberculosis spondylitis patients at the Gatot Soebroto Central Army Hospital (RSPAD). Data obtained from medical records of 75 samples. This study showed that male gender (50.7%), age group 21-29 years (29.3%), and normal nutritional status (33.3%) were the groups most affected by tuberculosis spondylitis (TB). Most types of work were housewives (28.0%). A total of 69 patients (92%) had no history of smoking and all patients had no history of consuming alcohol. Only 1 TB spondylitis patient had positive acid-resistant bacilli (AFB). A total of 41 people (54.7%) TB spondylitis patients were diagnosed through Magnetic Resonance Imaging / Computerized Tomographic Scan (MRI / CT SCAN) with the most TB spondylitis lesions found in the thoracic. The ability of MRI to diagnose is better than PCR and BTA.   Key words: Nutritional Status, Thoracic, Acid Resistant Basil
