A 69-year old male with cholangiocellular carcinoma (CCC) was assigned to our department for whole body PET/CT scan. $^{18}F$-FDG PET/CT images showed an intense hypermetabolic lobulating mass(SUVmax = 8.7 / size : 11.4 mm) in the right hepatic lobe with multiple metastatic lung nodules. We made three dimensional volume rendering fusion images by using advantage workstation 4.3 (GE health care) which provide quick anatomic overview and improve the planning process significantly.

This report is aimed to investigate the effect of Traditional Korean Therapy (TKT) in treating recurred breast cancer metastasized to lung. A 53-year-old woman who was diagnosed as left breast cancer and underwent surgery, adjuvant chemotherapy and radiotherapy in early 2009 was admitted for the treatment of recurred, metastatic lung cancer in late 2012. She was treated with TKT including acupuncture, moxibustion and pharmacopuncture. The effect was evaluated with positron emission tomogram and computed tomogram (PET-CT). The metastatic tumors in both lungs were disappeared after the treatment for about 2 months. These results suggest that TKT is a therapeutic method to treat metastatic lung cancer originated from breast cancer.

A 73-year-old non-small cell lung cancer (NSCLC) patient admitted due to cough, sputum, and dyspnea, aggravated a week ago. She was diagnosed as pneumonia based on the assessment of inflammation markers, chest X-ray and sputum culture. Computed tomography (CT) scan was conducted to exclude malignant tumor metastasis. At the initiation of treatment, considering underlying disease and inflammation marker level, herbal medicine and antibiotics were concurrently used and antibiotics had been discontinued after 10days. Using the monotherapy of herbal medicine in the next 6 days, chest X-ray showed remarkably decreased infiltration in right middle lung and right lower lung. This case represented additional improvement of chest X-ray when treated only with herb medicine after termination of antibiotic therapy and demonstrated the possibility of applying herbal medicine in patients with limited use of antibiotics.

Open lung biopsy was performed in thirty patients for the diagnosis and staging evaluation of interstitial lung disease during the period from January 1987 until December 1992. The age of the patients ranged from 14 to 71 years [mean 48 years], and the patients consisted of 14 males and 16 females. Preoperative FEV1`s were from 0.80 liter to 3.88 liters [mean 1.66]. Other non-invasive diagnostic studies such as PCNA, bronchoalveolar lavage, TBLB, and gallium scan were also done in addition to X-ray and high-resolution chest CT. Tweaty-eight were correctly diagnosed and 2 cases were not [diagnostic yield rate 93.3%]. Among the 28 cases,pathologic diagnosis influenced further treatment regimens and prognostic expectations in 23 cases [82.1%]. The diagnostic non-invasive studies other than open lung biopsy yielded a correct diagnosis without staging only in 5 cases. There was no mortality and only one complication, ARDS ; however, the patient recovered after 5 days ventilator support. Open lung biopsy, which is the gold standard for the diagnosis and staging evaluation of interstitial lung disease can be done safely and has value in clinical decision making. Also knowledge of the involvement of the lesion is important for proper selection of the biopsy site.

In this paper, we present a practical and essential method of using team projects for calculus. We, specifically, take into account the team project that calculate the volume of lung represented on CT scan images. We have demonstrated that the process of analyzing the images in a team project encourage studying numerical methods of integration for calculus. Also, we have used various technological programs(MATLAB, MATHEMATICA, MS Excel) to solve the team project.

Recent topics on quality assurance (QA) of X-ray diagnosis in Japan were reported in this presentation. These were related to mass screening mammography (MMG), lung screening CT (LSCT), skin injury caused by interventional radiology (IVR) and traceable system of dosimeters for x-ray diagnosis. In these successful stories, the author would like to stress the cooperation of all the medical am: clinical staff including medical doctors, radiological technologists, medical physicists, manufacturers of medical devices and others.

Congenital Cystic Adenomatoid Malformation [C.C.A.M. is rare, cause acute respiratory distress in the newborn infants. The histologic features are cystic areas and marked proliferation of terminal respiratory structures. On case 1, the patient was 8-month-old male, and suffered from acute respiratory distress and cyanosis. The pulmonary cystic lesion was detected in right lung at birth and has been evaluated since birth. The study for diagnosis were chest x-ray and chest CT. A right upper lobectomy was urgently performed and he was discharged with a satisfactory postoperative course. On case 2, the patient was 20-year-old female, and suffered from cough and sputum for 2 months. The study for diagnosis were chest x-ray, chest CT, and pulmonary angiography. The cystic lesion was detected in left lung and difficult to distinguish from pulmonary sequestration. A left lower lobectomy was performed and she was discharged with a satisfactory postoperative course. We report two cases of C.C.A.M. with differential clinical course.

A 2-year-old, female Pomeranian dog was referred for dyspnea. Thoracic radiographs revealed left-sided mediastinal shift, increased soft tissue opacity in the caudal aspect of left thorax with loss of the left diaphragmatic silhouette, and dorsal elevation of mediastinal structures and heart from the sternum by lung tissue. The left main bronchus was visualized as an air-bronchogram and observed to abruptly discontinue at the level of the 10th rib. Thoracic computed tomography (CT) revealed absence of the left lung parenchyma and left pulmonary vessels with a rudimentary left main bronchus. The case was congenital pulmonary aplasia diagnosed via radiography and CT.

The goal of this project is to achieve an accurate segmentation of the pulmonary tumors besides shortening the time and increasing the accuracy. Here, improved region growing (IRG) algorithm is introduced in order to segment the lung tumor with a sufficient accuracy in a shorter time compared to the other basics methods. This comprehensive algorithm was applied on 4 patients CT images and the results of the various steps on segmentation improvement shown 98% accuracy as compared to the basic algorithm. The combination of "multipoint growth start" produced a desirable outcome in accurately bounding the tumor. The proposed algorithm improved tumor identification by less than 13% along with a sufficient percentage of compliance accuracy.

A male mixed-breed dog of unknown age was presented with a history of bloody diarrhea and cachexia. Toxocara canis in vomitus was identified by a parasitologist. Hematology revealed low hematocrit, eosinophilia, and low albumin. Computed tomography (CT) revealed an enlarged pulmonary artery with an irregular wall, micronodules in the lung, and vicarious excretion of contrast medium to small intestine. CT scan was helpful for identifying lung lesions and the central organs of larval migration and also show vicarious excretion of contrast medium to the small intestine in T. canis infection.
