Review Article:
Congenital pulmonary artery anomalies: A review and approach to classification
Leslie E Hirsig, Priya G Sharma, Nupur Verma, Dhanashree A Rajderkar
J Clin Imaging Sci
2018, 8:29 (31 July 2018)

Congenital pulmonary artery anomalies are infrequent but given improved prenatal diagnosis and care, and neonatal surgical advances, over the past two decades are not uncommonly encountered by cardiothoracic imagers. An understanding of their etiology, classifications, associated anomalies, and surgical management can be helpful to avoid under or overdiagnosis. Timely diagnosis assisted by familiarity with imaging findings across modalities and recognition of surgical findings allows for medical management and surgical planning for these patients, with more patients reaching adulthood than ever before.

Pictorial Essay:
Tomosynthesis-guided core biopsy of the breast: Why and how to use it
Kyungmin Shin, Davis Teichgraeber, Sarah Martaindale, Gary J Whitman
J Clin Imaging Sci

Digital breast tomosynthesis (DBT) has become an important tool in breast imaging. It decreases the call-back rate while increasing the cancer detection rate on screening mammography and is useful for diagnostic examination of noncalcified lesions and for the evaluation of patients presenting with clinical symptoms. Management challenges and dilemmas that are encountered with abnormalities detected on DBT and lacking a sonographic correlate can now be addressed with tomosynthesis-guided core biopsy.

Original Article:
Linear atelectasis around the hilum on chest radiography: A novel sign of early lung cancer
Kerem Ozturk, Esra Soylu, Ugur Topal
J Clin Imaging Sci
2018, 8:27 (20 July 2018)
DOI
:10.4103/jcis.JCIS_35_18
PMID
:30123672
Background:
Linear atelectasis is a focal area of subsegmental atelectasis with a linear shape. Linear atelectasis may occur as a consequence of subsegmental bronchial obstruction.
Aims:
We propose an early roentgen sign of obstructing lung tumors, namely perihilar linear atelectasis, and ascertain whether this phenomenon could be used as a sign to detect radiographically occult primary lung cancer.
Materials and Methods:
We performed a retrospective review of 45,000 posteroanterior chest radiographs to determine the frequency of appearance and characteristics of perihilar linear atelectasis. The perihilar region of chest radiographs was evaluated for the presence of linear atelectasis. When linear atelectasis was found, the total thickness was measured. Student's
t
-test was used to evaluate statistical significance, correlating the thickness of atelectasis and the presence of obstructing central primary lung cancer.
Results:
Perihilar linear atelectasis was demonstrated in 58 patients. Atelectasis was caused by an obstructing tumor in 21 (36%) cases and a variety of other conditions in 37 (64%) patients. A statistically significant relationship (
P
< 0.001) was observed between the dimension of perihilar linear atelectasis and primary lung cancer, with 16 of 19 patients with thick (>5.5 mm) perihilar linear atelectasis found to have primary lung cancer.
Conclusion:
Thick perihilar linear atelectasis is a new diagnostic roentgen sign that suggests subsegmental bronchial obstruction. In this patient subgroup, who are otherwise asymptomatic, a persistent linear atelectasis can be due to primary lung cancer.
