- Echocardiographic quantification of myocardial perfusion after IV contrast is possible, based on the intensity of the received intermittent second harmonic signal. To investigate the influence of respiration on the intensity of myocardial signals, we examined nine patients with normal coronary angiograms. At baseline, end-expiratory and end-inspiratory images were obtained in broadband radiofrequency (RF) and intermittent second harmonic modes, the latter repeated during IV contrast at rest and at peak stress. In mid-septum at baseline, end-inspiratory integrated backscatter intensity was 4 dB higher (p < 0.05, both in second harmonic and fundamental domains) than end-expiratory intensity. In second harmonic imaging, contrast increased signal intensity by 4 dB (p < 0.05) in six examined segments, but the increase in the midseptal region (2 dB) was not significant. Contrast-enhanced intensity at end-inspiration was higher (3 dB, p < 0.01) than baseline intensity at end-expiration. We conclude that the increase in myocardial signal intensity during inspiration may resemble the contrast effect in intermittent second harmonic mode. The respiratory variation persists after contrast and may mask or exaggerate the effect of myocardial contrast.

På många stolar : Axel Nyström som arkitekt och kulturbyråkrat
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the dissertation is to examine the work of Axel Nyström (1792–1868), describing the distinctive features of his architecture and discussing his significance for Swedish architecture during the nineteenth century, as a teacher, theorist, administrator, and practitioner.Three main questions serve as a basis for the study: 1. What was Axel Nyström’s role as administrator and teacher? 2. How did he perceive architecture? 3. To what extent and in what way did his buildings influence and shape Swedish architecture?Axel Nyström was working in a time of change, as regards both architecture and society as a whole. Classicism was no longer the given model to emulate. Industrialism was gradually growing and a new bourgeois class was emerging. This led to new types of buildings and new demands for academically trained architects who could give a suitable architectural form to the public spaces of the new bourgeoisie.The quest for a contemporary style increasingly began to occupy architects and writers on the continent – a debate in which Nyström participated and which he transferred to Sweden. He was involved in architectural education, which he radically reformed, and he strove to bring about a redefinition of the concept of architect. Nyström played an important part in the emergence of a new role for the architect: from the eighteenth-century architect who had been a pupil of a master or had received his training in the military, to a professional with an academic education – thus pointing the way forward to the professional category that today’s architects constitute. Many of Nyström’s ideas can also be said to have been ahead of their time. A great deal of what would become a concrete reality in the second half of the nineteenth century was already expressed by him in the 1840s, for example as regards the use of genuine materials and an eclectic attitude to historical forms of architecture.

Antiken som ideal : Det antikiserande inredningsmåleriet och dess sociala funktioner i högreståndsmiljöer i Dalarna och Gästrikland 1791-1818
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on classical style wall painting in the late 18th and early 19th centuries. The study specifically involves the governor's official residence in Falun and nine manor houses in the Swedish provinces of Dalarna and Gästrikland, all of which were decorated in the classical style by local artist Johan Nils Asplind between 1791 and 1818. The patrons were early industrialists; all but one were ironworks owners. The main purpose of the thesis is to describe and analyse the classical style ornamentation and its social functions in the above-mentioned buildings. The thesis comprises four main chapters, the first of which briefly deals with the origins and development of 18th century classical style decorative wall painting in Sweden, its influences, and its ideals. The next chapter describes and analyses the Governor’s official residence in Falun in terms of its historical furnishings and decorated interiors. The third of the main chapters describes and analyses the classical style wall painting and its social functions within the nine manor houses. The last of the main chapters analyses the art of Louis Masreliez, in particular the studies created during his twelve-year-long stay in Italy in the 1770s and 1780s. The analysis arrives at a new interpretation of Masreliez’s extensive collection of Italian studies. Contrary to previous research, the thesis claims that the studies are the work of a history painter, not a decorative painter. This allows for a new understanding of the origins of the artist’s classical style interiors, where the use of ornamental engravings is emphasized as a complement to the many studies of the human body. Together with the earlier chapters, this interpretation also results in a less static understanding of the use of models, and the thesis examines them in a more multifaceted way than hitherto has been the case in art history.

Carl Christoffer Gjörwell 1766-1837 : byggnader och inredningar i Sverige och Finland
- 1994

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Carl Christoffer Gjörwell 1766-1837. Architecture and interior decorative art in Sweden and Finland from the time of Gustav 111 to that of Karl XlVJohan. The intent of this thesis is to map the life and work of Carl Christoffer Gjörwell. The point of departure has been the voluminous store of architectural drawings and documents, available primarily in state and local archives in Stockholm, but also in archives located elsewhere and in private hands. From 1803 until his death Gjörwell was active as city architect, and a rich collection of drawings and documents in the Stockholm City Archive illustrates this aspect of his work. He was also frequently employed by private individuals, and a collection of letters in the Royal Library from about 300 correspondents gives a good idea of the wishes and requirements that people had in regard to buildings at that time. Thanks to these letters, previously anonymous buildings, as well as renovations of buildings in Stockholm and mansions, can now he ascribed to Gjörwell. Letters and drawings are the basis for a chapter on his journey to Italy in 1794-96. French influence was great throughout Gjörwell’s life. Following his student period at the Art Academy he was employed as assistant to the French architect and stage set designer Louis Jean Desprez. This collaboration, which lasted until the death of Gustav III, was decisive for the earliest creations by Gjörwell. The French-Italian influence was further strengthened after the twoyear- long journey to Italy, where he spent most of his time in Rome. The voyage out by boat via Algiers and the return through Germany made lasting impressions, as well. During a month’s stay in Hamburg, Gjörwell met with the exiled French architect Joseph-Jacques Ramée daily. Following his return 1798-99 he designed two of his most important buildings, Abo Academy and a private palace in Stockholm for the master brewer Abraham Westman. Starting around the turn of the century, Gjörwell’s French impulses received a new orientation through J.-C. Krafft's and N. Ransonnette’s volume of pictures of French residential architecture from the 1780s and 1790s, and Percier and Fontaine’s publication of interiors from the late 1790s onward to 1812. Gjörwell owned both of these works and realized their ideas in, among his other works, the exteriors of manor houses. The clearest example of Percier’s and Fontaine’s influence can be seen in the royal bedchambers at Rosersberg and the Stockholm Castle, which were decorated for Karl XIII and his consort Hedvig Elisabeth Charlotta around 1810. The foreign examples made an impression on Gjörwell, who transformed them into Swedish reality that set the then current style. Characteristic of his architectural design is his ability to capture the current esthetic mood, while adjusting to the nature of the task and the owner’s desires and resources. He secured royal, private, local governmental and state commissions, and stands out, along with Fredrik Blom, as the most successful and versatile architect during the first four decades of the 19th century.

Regional mean systolic myocardial velocity estimation by real-time color Doppler Myocardial Imaging: A new technique for quantifying regional systolic function
- 1998

Tidskriftsartikel (refereegranskat)abstract
- A new color Doppler myocardial imaging (CDMI) system with high spatial and temporal resolution and novel postprocessing modalities has been developed that could allow quantifiable stress echocardiography. The purpose of this study was to determine whether regional myocardial systolic velocities could be accurately and reproducibly measured both at rest and during bicycle ergometry by using CDMI. Thirty normal subjects were examined with CDMI at rest, and peak mean systolic myocardial velocities (MSV) were measured for 34 predetermined left ventricular myocardial segments. Interobserver variability and intraobserver variability were established for all segments. Submaximal bicycle ergometry was performed in 20 normal subjects by using standardized weight-related increases in workload. MSV were measured at each step of exercise for 16 left ventricular stress echo segments. At rest, a base-apex gradient in regional MSV was recorded with highest longitudinal shortening velocities at the base. A similar pattern was noted for circumferential shortening MSV. Measurements were predictable and highly reproducible with low interobserver and intraobserver variability for 26 of 34 segments. Reproducibility was poor for basal anteroseptal segments in all views and mid anterior, anteroseptal, and septal segments in the short-axis views. During exercise, mid and basal segments of all walls showed a significant increase of MSV between each workload step and for apical segments between alternate steps. The resting base-apex velocity gradient observed at rest remained in all walls throughout ergometry. Thus a CDMI system with improved spatial and temporal resolution and postprocessing analysis modalities provided reproducible and accurate quantification of segmental left ventricular circumferential and longitudinal contraction both at rest and during exercise.
